Acid-Base Titration Experiment essays To titrate a hydrochloric acid solution of unknown concentration with standardized 0.50 M sodium hydroxide and to utilize the titration data to calculate the molarity of the hydrochloric acid, and the molarity. Prepare for lab. Put on apron and goggles. Take 50 mL of the hydrochloric acid solution of unknown concentration and about 100 mL of the standardized NaOH solution. Record the value in Table. Use suction bulb, pipet 10.0 mL of the HCl solution into a 250 mL Erlenmeyer flask, after rinsing your pipet with small amount of HCL first. Add 3 drops of phenolphthalein solution. Rinse a clean buret with approximately 15 mL of the standardized NaOH solution. Drain the buret and refill with standardized NaOH solution. Record the initial volume of the NaOH in the buret in your Table. Gradually dispense some of the standardized NaOH solution into the titration flask. Swirl the flask constantly. Continue adding NaOH, noting any changes in the flask. As the equivalence point approached, a pinkish color will appear, and the dissipate more slowly as the titration proceeds. Now add NaOH drop by drops. Stop when the addition of a single drop causes the solution to remain pinkish for 30s. Record the volume of NaOH needed to reach the equivalence point in your copy table 1, and repeat the procedure again from getting 10.0 mL sample of HCL and compare the result. Mix any leftover acids and bases together to neutralize, and pour down the sink with plenty of water. MOLARITY OF NaOH TRIAL 1 TRAIL 2 TRAIL 3 ...

Baggie Chemistry Experiments

Baggie Chemistry Experiments Overview An ordinary ziploc bag can unlock a world of interest in chemistry and in the reactions within and around us. In this project, safe materials are mixed to change colors and produce bubbles, heat, gas, and odor. Explore endothermic and exothermic chemical reactions and help students develop skills in observation, experimentation, and inference. These activities are targeted for students in grade 3, 4, and 5, although they may also be used for higher grade levels. Objectives The purpose is to generate student interest in chemistry. Students will observe, experiment, and learn to draw inferences. Materials These quantities are suitable for a group of 30 students to perform each activity 2-3 times: 5-6 plastic ziploc-style bags per lab group5-6 clear plastic vials or test tubes (may be used instead of baggies)1 gallon bromothymol blue indicator 10-ml graduated cylinders, one per lab groupteaspoons, 1-2 per lab group3 pounds calcium chloride (CaCl2, from chemical supply house or from store selling this type of road salt or laundry aid)1-1/2 pounds sodium bicarbonate (NaHCO3, baking soda) Activities Explain to the students that they will be performing chemical reactions, making observations about the results of these reactions, and then designing their own experiments to explain their observations and test hypotheses that they develop. It may be helpful to review the steps of the scientific method. First, direct the students to spend 5-10 minutes exploring the lab materials using all of their senses except taste. Have them write down their observations regarding the way the chemicals look and smell and feel, etc.Have the students explore what happens when the chemicals are mixed in baggies or test tubes. Demonstrate how to level a teaspoon and measure using a graduated cylinder so that students can record how much of a substance is used. For example, a student could mix a teaspoon of sodium bicarbonate with 10 ml of bromothymol blue solution. What happens? How does this compare with the results of mixing a teaspoon of calcium chloride with 10 ml of indicator? What if a teaspoon of each solid and the indicator are mixed? Students should record what they mixed, including quantities, the time involved to see a reaction (warn them that everything will happen very fast!), the color, temperature, odor, or bubbles involved... anything they can record. There should be observations such as:Gets hot Gets coldTurns yellowTurns greenTurns blueProduces gasShow students how these observations can be written down to describe rudimentary chemical reactions. For example, calcium chloride bromothymol blue indicator heat. Have the students write out reactions for their mixtures.Next, students can design experiments to test hypotheses they develop. What do they expect to happen when quantities are changed? What would happen if two components are mixed before a third is added? Ask them to use their imagination.Discuss what happened and go over the meanings of the results.

Use of Digital Media within Organisations Case Study

Use of Digital Media within Organisations - Case Study Example In the recent years, facing stiff competition in industries and the high need to cut costs while still maintaining efficiency in businesses has seen the rapid growth and development of digital solutions for businesses. A key area in which digital media has greatly been used by the various businesses is communication. Communication is a critical success factor in the business world and hence the development and improvement of digital media such as web videos, availability of e-books and social media have been key turnaround factors for business organisations. In the above mentioned case study involving virgin media, it is demonstrated beyond reasonable doubt that the use of digital media has a positive rather than negative impact on the performance of an organisation depending on the overall objective for the incorporation of digital media was. Here, the objectives of the study were to raise awareness of Virgin Media HD football packages through online mobile marketing and this was sp ecifically targeting the users of iPhones. The brand basically wanted to use a new, innovative and creative mobile marketing form in a bid to get the attention of football fans browsing the Guardian mobile internet website. Virgin media was working I partnership with an advertising agency, 4th street advertising. The main objective that was to be achieved was to get the information on virgin media HD football channels to a specific target audience which was football fans who owned iPhones. This was done through the execution of a well laid out strategy that involved exposing the target audience to the advertising message and a clear action that encouraged the recipients to learn more about the products and services offered by virgin media. Additionally, the advertisement campaign provided value addition with a calendar sync option that enabled the users with a fixture list of all games to be televised of the English Premier League. The intended purpose was to improve customer loyalt y and give then pride in being virgin customers. The banner bearing the campaign on the website was easy to use and access and it provided users with two calls-to-action. â€Å"Find out more about Virgin Media Football Packages† and â€Å"Sync televised games with calendar†. The call to action that allowed the audience to find out more about various other packages offered allowed the organisation to put across all or other products that the potential clients may not have been well aware of. The results obtained from the implementation of digital media in communicating to the target audience produced splendid results for Virgin Media. The creative execution drove high interactivity with the brand from the target audience. During the quarter to December after the launch of the digitized media in August, Virgin added over 100,000 Sky premium subscribers to reach a total of 725,000. As depicted clearly, clear and simple messages via digital media are a really positive way to communicate to potential customers. I chose to break down the in depth analysis of the effect of digital communication in this above briefly introduced scenario within in topics that depict every step of the process. Goal of Organisation The goal of Virgin media, according to the scenario, was to raise awareness of Virgin Media HD football packages that were in store for avid football fans via mobile advertising and targeting specifically iPhone users. The brand aimed to employ innovative

A Critique of Taylor's Concept of Multiculturalism in Relation to Essay

A Critique of Taylor's Concept of Multiculturalism in Relation to Nation Building - Essay Example The society is a framework within which different people interact to create various inclinations and trends which define the culture3. The world is a dynamic place and as changes occur in societies, there are numerous tendencies that makes it impossible for cultures to continue to be transferred from generation to generation. This therefore brings to play the concept of â€Å"cultural survival† which is concerned with the ability of a given culture to stand the test of time that comes with modernisation4. Professor Charles Taylor supports the communitarian school of thought which claims that the idea of individualism evolved as a consequence of some failures in the development of the modern Eurocentric society5. Due to individualism, the risk of cultural survival is now higher than it has ever been in the past. He holds that the replacement of communal structures with individualism is gradually causing the human race to lose important morals and values. As an antidote to this, communitarians believe that the social structures should be rebuilt and this can be done through enhancing different cultures in a given nation. This idea has become popularly known as the recognition of culture. Recognition of culture therefore refers to the respect of people's distinct cultures and allowing different people to practice their different cultures in a given nation. ... Taylor's argument, called the politics of equal respect implies that distinct cultures will have to be respected and allowed to thrive in a nation, even if it comes with wide differences. Theoretically, the recognition of culture means that if people from extremely different ends of the world come together in a given geographical area, they should be allowed to maintain their unique values, irrespective of how different they are. It is therefore obvious that this position of Taylor gives room for a wide diversity of possibilities which cannot go unchecked. In this paper, I examine the key debates of Taylor in relation to the concept of the recognition of differences in cultures. I will critically assess the validity of the communitarian views on the subject by comparing them to counter arguments and criticisms of his ideas. I will utilise various philosophical positions and ideologies of various thinkers and theorists and use them to validate or reject various propositions presented by Taylor and other communitarians. The paper argues that the idea of communitarianism is the best way for the survival of today's society and although there are some inherent challenges in it that threaten to prevent cohesion it is the only viable option in socializing children. The Basis of Taylor's Argument Taylor, in his book Ethics of Authenticity built a strong case against the existing systems and structures in the modern society. He identifies that there are three main 'malaises' or cankers in our modern society that are potentially dangerous to the current society7. The first malaise is the concept of individualism. People tend to have the freedom to decide what is right and choose to do it for themselves. Thus, whatever is convenient to an individual

Health Care Reform Recommendations Essay Example for Free

Health Care Reform Recommendations Essay The topic of heath care reform is a highly debatable one. Many different organizations have diverse ideas on what is essential to ensure a successful healthcare system is developed in the United Sates. After reading recommendations to advance health care reform from the Mayo Clinic’s (2008), The Wall Street Journal’s Health Care CEO Council (2008), consisting of CEO’s from multiple different medical organizations, and America’s Health Insurance Plan (AHIP)(2007), the following is a list of three recommendations considered by all to be valid ideas for healthcare reform: 1. Access: Universal Health Insurance A. A comprehensive health care reform recommendation of providing universal access to affordable, guaranteed, quality insurance plans for those not covered by employer-based programs. This plan would require individuals to buy insurance, giving them choice, accessibility, control, and peace of mind. B. This reform would require adults to purchase private health insurance for themselves and their families. Employers could continue to participate by buying insurance for their employees or giving them stipends to purchase it. However, the individual would own the insurance. C. Appointing and independent agency to provide coordination, oversight and education for individuals choosing insurance options. 2. Quality: Reform the Payment System A. Change the reimbursement system to reward preventive care and evidence-based care, and extend government efforts to no longer reimburse inappropriate, unsafe or wasted care. Define and measure desirable outcomes for most common diseases. B. Payment to providers should be changed in order to improve health and minimize waste. Create payment systems that provide incentives for various providers to coordinate care, improve care, and support informed patient decision-making. Models of payment should be developed based on the success of chronic care coordination, care coordination teams, shared decision-making and episode-based payment. C. Change Medicare to a pay-for-value model. Redistribute Medicare payments to favor physicians who perform well, as opposed to the current system that rewards volume not value. Paying providers based on value can help produce desired results such as: great outcomes, safety, and service at an affordable cost over time. 3. Affordability: A. Poorly coordinated care also drives up costs when individuals seeing several health care practitioners receive the same diagnostic tests and procedures multiple times because one physician did not know that the other already had conducted them. Access to information that compares the effectiveness and cost of treatments: give providers, patients and purchasers access to a trusted source where they can find up-to-date and objective information on which health care services are most effective and provide the best value. B. Provide positive personal health habit incentives. Lifestyles characterized by smoking, poor diet, and lack of exercise leading to obesity are key contributors to high health care costs in the United States. Childhood obesity significantly increases the risk of cardiovascular disease in adulthood (CDC, 2006) and according to a study done by the Office of the US Surgeon General (2007), the complications from obesity: cardiovascular disease, diabetes and cancer are estimated to cost $92 billion (Finkelstein, 2003) in lost productivity per year whereas estimates suggest that the health consequences of smoking may lead to more than $75 billion per year in medical expenditures. C. Provide tax credits to individuals, families for the purchase of insurance, and to small business owners that provide medical coverage to employees. On January 24, 2007, while speaking about healthcare at Families USA, a healthcare advocacy group, then Senator Obama said â€Å" The time has come for universal health care in America [ ] I am absolutely determined that by the end of the first term of the next president, we should have universal health care in this country. (Wikipedia, n. d). Senator McCain however, proposed tax credits and open-market competition as opposed to government funding control (Wikipedia, n. d. ) In comparison, President Obama and Senator McCain, had similar plans in regards to cost and quality improvement. Both parties suggested the adoption of medical malpractice reforms, allowing drug re-importation, focusing on healthcare costs as a reflection of quality service, prevention and care of chronic conditions, and development/deployment of HIT. In addition to similarities in cost and quality improvement, both also believed that prevention is the key to creating a healthier population. Senator McCain focused more on individual responsibility in maintaining and healthy lifestyle whereas President Obama supported increased funding to community based preventive interventions. Overall, a comparison of both parties preliminarily health reform plans reflect multiple similarities in general ideas of needed reforms to the United Sate’s current healthcare system. Whether by adopting a universal healthcare system or implementing changes to the current system; extending coverage, lowering costs, and improving quality of care are all issues agreed upon by both parties as needing attention.

Ellen Foster :: essays research papers

At the age of ten, most children are dependent on their parents for everything in their lives needing a great deal of attention and care. However, Ellen, the main character and protagonist of the novel Ellen Foster, exemplifies a substantial amount of independence and mature, rational thought as a ten-year-old girl. The recent death of her mother sends her on a quest for the ideal family, or anywhere her father, who had shown apathy to both she and her fragile mother, was not. Kaye Gibbons’ use of simple diction, unmarked dialogue, and a unique story structure in her first novel, Ellen Foster, allows the reader to explore the emotions and thoughts of this heroic, ten-year-old girl modeled after Gibbons’ own experiences as a young girl. Kaye Gibbons’ experiences as a child are the foundations for this breathtaking saga of a young girl’s tragic memories of her childhood. As with Ellen, Gibbons’ parents both died before she was twelve-years-old forming the basis of the plot and themes of this novel. The fond memories she possessed of her mother and the harsh ones of her father are reflected in the thoughts and actions of Ellen. The simplistic and humble attitude that both Gibbons and Ellen epitomize in the novel is portrayed through diction and dialogue throughout the novel allows the audience to gain a better understanding and personal compassion for both the character and author. The novel is written in a short, choppy sentence structure using simple word choice, or diction, in a stream of consciousness to enable the reader to perceive the novel in the rational of an eleven-year-old girl. One short, simple sentence is followed by another , relating each in an easy flow of thoughts. Gibbons allows this stream of thoughts to again emphasize the childish perception of life’s greatest tragedies. For example, Gibbons uses the simple diction and stream of consciousness as Ellen searches herself for the true person she is. Gibbons uses this to show the reader how Ellen is an average girl who enjoys all of the things normal children relish and to contrast the naive lucidity of the sentences to the depth of the conceptions which Ellen has such a simplistic way of explaining. Gibbons’ and Ellen’s harrowing past is related in the novel through Ellen’s inner thoughts and the dialogue between characters.

Civil Liberties, Personal Freedoms, and US Law Enforcement Essay

Americans would like to believe that they have freedoms that are available to people in no other country on earth. In a very real way, this statement is true. We are free to criticize the people who govern us in a manner unavailable in most countries, without expecting retribution. Public access is available to many, if not most government buildings. The American process of governing is relatively transparent. All of these things have created a great expectation of freedom, or at least liberty, in this country. And yet, the nature of liberty and freedom, as well as how these thing interact with law enforcement, are not well understood by many Americans. Freedom vs. Liberty Although the concepts of liberty and freedom are related, they are not the same. The United States of America, as noted above, allows many kinds of freedom. There is freedom â€Å"from† things, such as absolute government control of lives and freedom â€Å"to† things, as in freedom to choose a school or a career, rather than having such a thing assigned. Freedom consists of the ability to move about at will, personal liberty, and civil liberty. In philosophical terms, freedom is the â€Å"power to exercise choice and make decisions without constraint from within or without; autonomy, self-determination (â€Å"freedom,† n. d. ). Although liberty is used as part of the definition of freedom, they are not identical concepts. Liberty, however, is freedom from such things as outside control in an individual’s personal choices, from captivity, and â€Å"freedom from arbitrary or despotic government or control† (â€Å"liberty, n. d. †). It can be seen, then, that of the freedoms that Americans expect to have are composed of both freedom–the freedom to†Ã¢â‚¬â€œand liberty–the â€Å"freedom from. Without civil liberties, Americans would find themselves facing an increased number of forcible actions from their own government, as well as potential attempts to infringe upon those liberties from outside. Americans and Civil Liberties Americans have always taken their civil liberties seriously. State seals and mottos refer to liberty. The New Jersey state motto is â€Å"Liberty and Prosperity,† while text on the Massachusetts Great Seal once read, â€Å"By the sword we seek peace, but peace only under liberty. † Patriotic songs refer to the nation as being the â€Å"sweet land of Liberty. From the beginning, then it can be assumed that Americans have expected â€Å"freedom from,† liberty, particularly freedom from tyranny. In today’s world, the concept of tyranny can take many forms. Racial profiling is often considered to be one form of tyranny, although it is not always simple to assess when it occurs (Barkan, 2005). Research from the Institute for Public Policy and Social Research [IPPSR] indicates that Americans largely favor the protection of civil liberties, even when responding after a crisis. However, the degree to which people are willing to accept changes to policies that affect civil liberty will vary based on race and ethnicity, political ideology, the area in which they live, and more (ISPPR, 2002). One significant influence on whether these changes should occur is that of trust in law enforcement (ISPPR, 2002). According to xxxx (2002): citizens with low trust in local law enforcement give 6. 7 (out of 8) pro-civil liberties responses, while citizens with moderate trust give 5. 4 pro-civil liberties responses, and citizens with high trust give only 4. 7 pro-civil liberties responses. p. 4) These findings are significant to this paper in that the lack of trust in local law enforcement seems as if it is often both the cause and the result of the effects of policing on the community. If people have contact with policing agencies that allows them freedom to do something, then they feel comfortable with the amount of civil liberty that they have and may consider adjustments to that liberty. If individuals in a society feel as if they already have little freedom, then they will necessarily feel as if the amount policing that is permitted should not vary, at least not by increasing it. New Policing† The methods for policing seem to be changing worldwide, shifting from public policing to private policing. These changes seem to be occurring primarily in democratic societies, which have looser control over individuals’ lives. According to Ashcroft (2001), democratic governments can accommodate diverse centers of power, whereas authoritarian regimes cannot. Democratization facilitates restructuring by providing political space into which it can grow. As political pluralism increases, so too do the auspices that want to share responsibility for policing. (p. 28) Why, then, are democratic nations more difficult to police than others might be? The answer appears above: authoritarian regimes maintain control of their citizens by coercion and force, which does not permit decentralized policing of their nations. They do not have the freedom from, not in many capacities, and for this reason their citizens are not at liberty to act or to decide what changes that the government that can affect their lives. ecause they do not have the freedoms â€Å"from† that Americans have, the government can decide what police actions must be taken, when they will be taken, and what form these actions will take. The reason that Americans are so shocked by such events as the Kent State actions, the actions taken at Ruby Ridge or those taken against the Branch Davidians, is that they appear to be so totalitarian. Americans expect better of their le aders and respond with words that indicate they feel betrayed and, sometimes, those betrayed feelings result in votes being withheld. Democratic nations are so difficult to police because their policing mechanisms are so diverse and are so dispersed. In addition, actions taken against the citizens require a reason and a precedent, unlike policing actions in authoritarian or totalitarian states, which need no apparent precedent to act. Conclusion Democratic nations require balance between the citizens, their government, and their policing agencies. Citizens must feel that they have value and that they are safe from unprecedented police actions, even from their own government. Such nations are difficult to police because only authoritarian nations is it possible to have access to the â€Å"easy† method of policing that involves force. While it is not impossible even for a democratic nation to have policing actions that involve force, they incite comment because they are unusual and frequently cause outrage. Policing a democratic nation is difficult because democracy is hard. To accept policing that negatively affects either freedom or liberty–or both–results in a nation that has fewer civil liberties, as well.

Learning Team A Reflection Essay

Throughout this course, we established a foundation in understanding Business Information Systems. This week’s objectives were to describe how wireless technologies are used in the workplace and how to use spreadsheets in business situations. While some members of Team A were well versed in Microsoft tools, others had their first lesson on Microsoft’s Excel and Access fundamentals. Team A’s members range from a project manager who attained their Associate Degree in Computer Programming, a logistics specialists for Amazon.com, a employee in the Hilton Hotel industry, and a wine educator working in hospitality—all very different fields with varying levels of information systems background. While for some it was a review, Team A can all agree that each and every one of us gained a better understanding on how and why information systems accomplish business objectives. Cheryl knew the degree in which wireless technologies kept users plugged into the World Wide Web. She was aware that smartphones and their many accessories allowed users to access their emails, schedules, mobile banking and participate in e-commerce as well as make online payments—she learned that M-commerce another growing trend. Due to telemedicine, modern technology has allowed the medical world to provide assistance via videoconferencing. In addition, she learned that setting up and using access points to create meshed networks called a Wide Area Network (WAN) (Rainer & Cegielski, 2011). Xavier learned the relevance of wireless technology in everyday life. More specifically, he learned of the different functions of varying satellite types to communicate information. Kelly learned about the two basic operations of data mining. According to Rainer and Cegielski (2011), data mining functions in  Ã¢â‚¬Å"predicting trends and behaviors and identifying previously unknown patterns† (chap. 11). Angeliza discovered that Wi-Fi was abbreviated for Wireless Fidelity as well as the synchronization of using Microsoft Excel with Access. With the objectives of Week 3 in mind, Team A members have found varying ways in which we can apply what we have learned in the classroom into our professional or personal lives. As a project manager, Cheryl can utilize Excel to track cost of goods (COGS) inventory. As a logistic specialist, Xavier can use spreadsheets in generating employee lists and creating reports to reflect the volume of freight used on a daily basis. As a team member in hospitality, Kelly can use data mining to track hotel guests’ sign up and preferences. In customer service, Angeliza can use the point of sale system to analyze the day’s sales and returns (Rainer & Cegielski, 2011). The learning activities and readings have left each member of Team A with a little more knowledge than we had previously. Cheryl knows that Microsoft Excel and Access are a perfect duo: Excel creates the tables that can be exported to Access where the data is analyzed. Xavier learned how to more effectively incorporate spreadsheet into his daily work routine. Kelly understands the role of wireless information systems in the creation of invoices for clients and making it easier to calculate daily cash sales. Angeliza learned that she doesn’t need to be an IT specialist to analyze data from Excel with Access. Despite our different backgrounds, Team A members can agree that we all gained a better understanding on how Information Systems plays into effectively and more efficiently completely business goals. Week 3’s lesson on spreadsheets and wireless technologies makes us more proficient in the language of information systems in the workplace and in our daily lives. Reference Rainer, R.

Celsius Temperature Scale Definition

Celsius Temperature Scale Definition The Celsius temperature scale is a common System Internationale (SI) temperature scale (the official scale is Kelvin). The Celsius scale is based on a derived unit defined by assigning the temperatures of 0 °C and 100 °C to the freezing and boiling points of water, respectively, at 1 atm pressure. More precisely, the Celsius scale is defined by absolute zero and the triple point of pure water. This definition allows easy conversion between the Celsius and Kelvin temperature scales, such that absolute zero is defined to be precisely 0 K and  Ã¢Ë†â€™273.15  Ã‚ °C. The triple point of water is defined to be  273.16  K (0.01  Ã‚ °C; 32.02  Ã‚ °F). The interval between one degree Celsius and one Kelvin are exactly the same. Note the degree is not used in the Kelvin scale because it is an absolute scale. The Celsius scale is named in honor of Anders Celsius, a Swedish astronomer who devised a similar temperature scale. Before 1948, when the scale was re-named Celsius, it was known as the centigrade scale. However, the terms Celsius and centigrade dont mean precisely the same thing. A centigrade scale is one which has 100 steps, such as the degree units between freezing and boiling of water. The Celsius scale is thus an example of a centigrade scale. The Kelvin scale is another centigrade scale. Also Known As: Celsius scale, centigrade scale Common Misspellings: Celcius scale Interval Versus Ratio Temperature Scales Celsius temperatures follow a relative scale or interval system rather than an absolute scale or ratio system. Examples of ratio scales include those used to measure distance or mass. If you double the value of mass (e.g., 10 kg to 20 kg), you know the doubled quantity contains twice the amount of matter and that the change in the amount of matter from 10 to 20 kg is the same as from 50 to 60 kg. The Celsius scale does not work this way with heat energy. The difference between  10  Ã‚ °C and 20  Ã‚ °C  and that between  20  Ã‚ °C and 30  Ã‚ °C  is 10 degrees, but a  20  Ã‚ °C temperature does not have twice the heat energy of a  10  Ã‚ °C temperature. Reversing the Scale One interesting fact about the Celsius scale is that Anders Celsius original scale was set to  run in the opposite direction. Originally the scale was devised so that water boiled at 0 degrees and ice melted at 100 degrees! Jean-Pierre Christin proposed the change. Proper Format for Recording a Celsius Measurement The International Bureau of Weights and Measures (BIPM) states that a Celsius measurement should be recorded in the following manner: The number is placed before the degree symbol and unit. There should be a space between the number and the degree symbol. For example,  50.2  °C  is correct, while 50.2 °C or 50.2 °Ã‚  C are incorrect. Melting, Boiling, and Triple Point Technically, the modern Celsius scale is based on the triple point of Vienna Standard Mean Ocean Water and on absolute zero, meaning neither the melting point nor boiling point of water defines the scale. However, the difference between the formal definition and the common one is so small as to be insignificant in practical settings. There is only a 16.1 millikelvin difference between the boiling point of water, comparing the original and modern scales. To put this into perspective, moving 11 inches (28 cm) in altitude changes the boiling point of water one millikelvin.
