Latent Heat of Vaporization of Water Essays
Latent Heat of Vaporization of Water Essays Latent Heat of Vaporization of Water Paper Latent Heat of Vaporization of Water Paper Uncertainty in measuring time was  ±0. 01s according to the stopwatch but while measuring mass you have to first look at the time in stopwatch and then the mass in the electronic balance and because humans cannot react instantly it is estimated to be  ±1s. Uncertainty in measuring mass of the water was  ±0. 1g because it was measured using a weighing machine with the  ±0. 1g uncertainty. The graph of mass of water evaporated over time is linear because the best fit line passes through all error bars. From the calculations the specific latent heat of vaporization of water is calculated to be 2500 J/g  ±60 J/g. The literature value of specific latent heat of vaporization of water is 2260 J/g, which is quite low. The total percent error is 10. 6% and the total percent uncertainty is 2. 5% which is quite low compared to the percentage error. 2. 5% uncertainty means the final result can be  ±2. 5% off. That means the total error caused by uncertainties is 2.5%, rest is from systematic errors. One of the biggest systematic errors could be the heat loss from the water to the atmosphere. A well-insulated plastic kettle was used to boil the water so there will be minimum heat loss from water to kettle and kettle to surroundings. If the heat is lost to the surroundings from water, it means that the power supplied by the kettle is not completely used to boil water as it is lost in the surrounding so the power supplied is less than 1000W. While recording the mass of water, the mass of the water in the electronic balance was not constantly decreasing. Sometimes it increased, sometimes it decreased slowly and sometimes rapidly and because of this there was a high error in collecting data. An electronic balance with high mass capturing should have been used for better results. The electronic balance used did not have a wide base and the kettle used to boil water was overturning it which also can result in high error. An electronic balance with wide base should be used for more accurate results.

A comparitive Study of Clinton's and George Bush's Economic Policies Essay
A comparitive Study of Clinton's and George Bush's Economic Policies - Essay Example Bush supporters argue that Clinton inherited a booming economy on the upswing from the previous Reagan/Bush presidencies then ran it into the ground for which George W. now takes the blame. Many Clinton backers disagree taking the position that the current Bush administration has instituted a faith-based economic policy; that Armageddon will happen soon so it doesn’t matter how the country’s economy is managed. To give total credit or blame to one person for every aspect of the nation’s economic condition is hardly a credible stance. However, this paper will compare the two presidents’ economic policies as they relate directly to the end result in similar categories as a means to compare their successes and failures on an even playing field. To that end, this discussion provides an extensive view of the economy over the previous 12 years spotlighting on percentage changes of several economic indicators rather than total number. The steady creation of employment opportunities is one of the most telling signs of a country’s economic condition. According to the Bureau of Labor Statistics, the number of jobs increased 2.38 percent per year under Clinton, but it has decreased 0.17 percent per year in the years Bush has held office (Atkinson & Hutto, 2004). The Bush administration claimed that the economy was on a downturn following the Clinton presidency then was further hindered by the attacks on the World Trade Center in 2001. Bush sold the idea of tax cuts to the public predicting that this step would help to stimulate the economy by creating 3.7 million jobs in 2003, but produced only 1.7 million, fewer than the number of births in the country that year (Council of Economic Advisors, 2003). By contrast, 22 million jobs were created during the eight years Clinton was in office. The tax cut concept was not based on sound, objective economic analysis, rather it was an ideology borrowed from the equally failed

Entrepreneurship & Innovation - Essay Example This is particularly a niche market, since traditionally, food shops offer meat foods that really do not emphasize on the health factor in their menus.

Of Mice and Men Essay Essay Example for Free
Of Mice and Men Essay Essay Throughout the book, â€Å"Of Mice and Men†George is Lennie’s everything! From dusk to dawn he is Lennie’s caretaker, friend, and he also works in place of himself and Lennie, too! He doesn’t have the easiest job in the world, either. He is faced with many challenges throughout the book. I do believe that towards the end George was finally getting enough, and he was getting tired of watching Lennie struggle. It got the best of him in a way. George has a job as a ranch hand out on the ranch. He does a little bit of everything. From making sure that the animals are in good health, and to helping the boss with anything he needs. George even watches over the slaves, to make sure they are doing what they need to be doing and are staying away from the whites. He carries a lot of responsibilities! He is also doing Lennie’s job at the same time. As we found out very quickly, Lennie is not the best at doing the task, due to his mental illness. He doesn’t know his strength, and tends to hurt/kill people and animals. Lennie has a heart of gold, and means absolutely no harm. Because of Lennie’s mental state, he needs a caretaker. George has been the one to step up to the plate and take that position. They got kicked out of Weed because Lennie went to feel a lady’s dress, and she accused him of rape. George somewhat felt guilty because as his caretaker it is his responsibility to make sure and keep an eye on him. George has to keep a close eye on Lennie and make sure that he is doing right. Any wrong thing that he may do could easily fall back on George, and they can lose everything, such as their job and shelter. At the end of the book, George had had enough of watching Lennie do wrong. He knew that after killing Curley’s wife, it could be something much worse, and being the friend he was he couldn’t watch him go through that anymore! As a friend, George is Lennie’s everything! Throughout the book, George was Lennie’s only true friend. He understood him, when everyone else didn’t. George knew when he messed up, but he still treated him like a best friend. He was more than just a caretaker, he was like a brother! I give props to George! He had been around the world and back with Lennie and he still loved him for the person he was. Even when he killed things, he was still there and didn’t think of him any less. Now that my friends, is a TRUE friend! This book was very touching, and sad. It helped open my eyes to realize that there really are people out there who do wrong, but don’t mean to. You may be proven guilty, but that doesn’t mean that you aren’t innocent. George really was a great friend to Lennie! He had a lot of responsibility on his shoulders! He would be one to look up to. Next time you see someone do wrong, you need to stop and ask yourself, â€Å"Did they really mean that?â€

Thirty Years War Essay -- History Euope War European Historical Essays
Thirty Years War Philip, Spanish kings. Philip I (the Handsome), 1478-1506, king of Castile (1506), was the son of Holy Roman Emperor Maximilian I and Mary of Burgundy. He inherited Burgundy and the Low Countries from his mother and was titular joint ruler of Castile with his wife, Joanna. But her father ruled these lands as his regent, so he contested (1504) Ferdinand's regency and assumed (1506) joint rule of Castile with his wife. Philip's early death, however, and his wife's deteriorating mental condition allowed Ferdinand to resume joint control of Castile. The Low Countries passed to Philip's son, who later became Holy Roman Emperor Charles V. Philip II, 1527-98, king of Spain (1556-98), king of Naples and Sicily (1554-98) and, as Philip I, king of Portugal (1580-98), centralized authority under his absolute monarchy and extended Spanish colonization to the present S United States and the Philippines (which were named after him). From his father, Holy Roman Emperor Charles V, he inherited Napl es, Sicily, the Low Countries, and other territories. After the death of his first wife, Maria of Portugal, he married (1554) Queen Mary I of England and drew that nation into his father's war with France. Following Mary's death (1558), he married Elizabeth of Valois and concluded the war with France in 1559. Philip used the Inquisition to repress the Moriscos and assure Spanish religious unity. He dealt with the Dutch revolt in his Low Countries domain by reconquering the southern half of the country. English support of the rebels and their persistent attacks on Spanish ships led him to plan an invasion of England by the Spanish Armada (1588), which was ignominiously defeated. Earlier, he succeeded in conquering Portugal (1580). Despite his conquests and the influx of gold from America, the cumulative effects of depopulation, colonial overexpansion, and burdensome taxation debilitated Spain by the end of his reign (1598). Philip was a hardworking bureaucrat with a capacity for infi nite detail, and though his administration was generally just, his bureaucratic absolutism inevitably created discontent. His court was at the Escorial. Philip III, 1578-1621, king of Spain, Naples, and Sicily, and, as Philip II, king of Portugal (1598-1621), lacked the intelligence and capacity for work of his father, Philip II, and left the actual government to the duque de Ler... ... The Duchy of Wà ¼rttemberg alone had lost almost two thirds of its population from hunger and disease, murder and killing. In 1618 it had 350,000 inhabitants, in 1648 just 120,000. The following examples come from the Mà ¼nsingen district and show the numbers of married couples and buildings before and after the war:      Married Couples     Houses and barns City of Mà ¼nsingen     191     96     240     157 Apfelstetten     56     15     74     29 Auingen     87     25     115     49 Bà ¶ttingen     64     14     82     39 Hundersingen     45     3     54     5 Mehrstetten     132     26     156     68 Mundingen     48     10     35     23 An important outcome of the Peace of Westphalia was that now, along with Catholics and Lutherans, the Reformed were also tolerated. This was important for the Palatinate. For one part of the southwest, a peace of 150 years began. On the Middle Neckar, in the whole Upper Rhine area and especially in the Electorate Palatine the wars waged by the French King Louis XIV from 1674 to 1714 caused further terrible destruction. France penetrated through acquired possessions in Alsace to the Rhine border. Switzerland separated from the German empire.

Human Resources function Essay
In this assignment we were instructed to select a business in which to analyze its Human Resources function. After a long deliberation I chose to discuss Tesco. There are several factors that influenced my choice one of these factors was accessibility of information on Tesco. I feel that in order to produce a vivid and constructive assignment, accessibility of background information is essential. Another factor that influenced my choice of business was familiarity, and the fact that I am a regular customer of Tesco’s and have friends and relatives that work for the company presently or have done in the past makes producing an in depth assignment on Tesco’s Human Resource function, much more straight forward than if I had no awareness of the company at all. Tesco is a nationwide food retailer and has stores all across England as well as some parts of Europe it specializes in the sale of food and other household goods and necessities. Tesco is today’s leading food retailer in the country, however without good employees the company would have never reached its current status and this is the case of most of the nations leading stores and companies. It is a well known fact that human resources is the most significant resource to any large scale business or company overweighing capital, buildings, land, equipment and materials or any other resource. The purposes of human resources are to attract and keep good, hard working, high quality staff. And the other purpose of the human resource sector is to dismiss low quality, lazy unhelpful workers who are known as liabilities to the company. This is important to a company like Tesco for high quality staff is hard to come by so it is important that the functional area under which the human resources is in does its best to retain good, hard working internal customers for as I previously mentioned the staff is considered to be the company’s most significant resource. Another purpose of the human resources section in Tesco is to train and develop all their employees to enable them to reach their full potential and do the work in which they have been employed to do to the best of their ability. By Tesco training and developing their staff even the members of staff who are not the best at their jobs develop into sufficient high – quality workers and this benefits Tesco for they could possibly save money, for instead of employing 10 workers to do one particular job for instance they can use 4/5 of the employees that they have been trained for the employees would be highly sufficient and would probably do the work quicker and of a higher quality than 10 new employees and in addition save Tesco money. Another purpose of the human resources sector is to ensure that Tesco’s avoids unlawful or unfair discrimination. This purpose is important for the company for if discrimination was not unavoidable by the human resource sector many workers would find Tesco an unpleasant working environment and when they come to work would put limited effort into their job hence developing a bad name for the organization. The last purpose of the human resource sector, which I am going to put into perspective, is to ensure that Tesco operates within the law in relation to employment and health and safety. This purpose is very significant for it provides employees with information about laws which apply to health and safety and employment therefore they wont violate these laws unknowledgeable. Like most functional areas in Tesco the human resources sector also have activities that staff within the human resource sector have to undergo. One of the human resources activities in Tesco is to recruit, retain and dismiss staff this is an important activity and requires a lot of attention. The human resources center has to deal with the recruitment of staff, they have to hold interviews and undergo research for applicants who want to work for Tesco. This activity requires not only interviews and research but it also requires the human resources sector to advertise placements. Another thing this activity requires is to retain good high quality staff; the human resources can manage this by acting as consultants and helping members of staff in everyway possible. In addition the human resources have a duty to ensure that Tesco maintains a good working environment and therefore form good working relationships between staff so there is an endless pleasant felling in Tesco and it would prevent good workers from leaving Tesco as a result of hostility within the organization. It is also very important that Tesco allows its internal customers to have sick leaves lunch brakes etc. to relieve any pressures of work which the employees could fell they would need to resign. One more activity, which I am going to put in to perspective, is the dismissal of staff. The company has to deal with many incidents of staff dismissal every year but it is the human resources sector that deals with them directly. It is the human resources job to give warnings to employees i.e. verbal warnings for lateness and then written warning etc. so when a employee violates Tesco’s company policy whatever it may be, it is then the human resources responsibility to provide a notice to the member of staff who has violated company policy that they have been dismissed from the company in other words â€Å"sacked†. Another set of activities, which the human resources sector has to deal with, is the training, development and promotion of employees. The training of employees in Tesco is done solely by the human resource sector. It is human resource that decides what kind of training a particular employee needs, when the particular employee needs training and how long will the employee need to be trained for. For instance if a member of staff was appointed trainee manager of Tesco it would then be the responsibility of the human resource sector to decide how long the employee should train for depending on the particular employees personal ability. The training of Tosco’s internal customers is part of its employees development, the reason for this is because the training of employees is to do with the development of skills i.e. communication with customers. The provided training at Tesco’s helps develop skills for many employees every year for Tesco’s nurtures all its employees and gives them skills to carry along with them to future employment when they leave Tesco if they should leave. Another aspect, which the human resources sector in Tesco has to deal with, is the promotion of its staff. I feel every member of staff regardless of their role whether they are toilet cleaners or till assistants are entitled to promotion after being part of a company such as Tesco for a certain amount of time. However, the statement I have just made is not how Tesco runs its promotion opportunities there are other factors that Tesco’s human resources look into when considering an employees promotion. One factor that the human resources look at is how interested you are with your work and how interested you are with Tesco itself, the human resources look for employees who have actually gained an interest with their work and the organization when selecting an employee to be promoted, this is important for Tesco for an employee who has an interest with the company and their job is likely to put more effort and sufficiency in their work than somebody who has a low amount of interest for the company and their job. Tesco’s human resources sector also looks at a promotion candidate’s ability to get along with their fellow employees. This is also an important factor for Tesco when deciding to promote a member of staff to a higher role for they want to promote friendly/pleasant characters as opposed to hostile/rude employees who don’t get along with anybody in their current role let a lone a higher role where they will be in contact with more employees. Another factor that the human resources look at is the employee’s ability to manage their current job exceedingly well. In my own personal opinion this is the most significant factor apart from †how long the employee has been working with the company for†when deciding to promote a member of staff into a higher position. I feel this is the most important factor the reason being is that you cannot possibly promote a member of staff onto a higher position with higher pay cheque and higher responsibility when they are struggling or just about managing with their current job. The next set of activities that the human resources sector have to undergo in Tesco that I am going to put into perspective in this assignment is the monitoring and maintenance of good working conditions. Good working conditions are enforced by Tesco’s human resource sector and list of the conditions are presented to all new employees when they start at Tesco. Some of the information presented to the new employees on the list of terms and conditions include, the address of their work placements, the employees hours of work, the employees wage and also additional payments such as commission, bonuses and overtime. Also in them list of terms and conditions are employees holiday entitlements per year both personal and statutory days e.g. Christmas, whether the employee will receive sick pay and if so on what basis i.e. only with a Doctors note. In addition the list of terms and conditions, which are presented to all new employees at Tesco’s, include pension rights and any f ringe benefits, for example share rewards staff vouchers etc. The working conditions are regularly inspected by staff from the Human resource sector to ensure that the working conditions in Tesco is kept at a superior standard to ensure that employees can do there work well without worrying about any obstacles distracting them from their work. The physical environment such as good lighting and ventilation, modern furnishings and equipment, adjustable heating, low noise pollution and a restful color scheme. In Tesco, in their attempt to make sure there is an endless pleasant environment and good working conditions in the store the human resources offer employees personal services such as free medical screening and the availability to talk to counselors whenever they are experiencing any personal problems. By Tesco helping their internal customers in this way it can help to relieve a lot of tension and maintain a good working environment for Tesco’s employees. The last activity I am going to put into perspective that Tesco’s human resource sector undergoes is health and safety. The UK law requires internal customers as well as employers to conform to the health and safety legislation. Like most organizations Tesco have a health and safety officers who advises the managers at Tesco about their responsibilities in regards to the health and safety law it is, also it is the role of the health and safety officer to ensure all employees are kept informed about the health and safety law via the manager. In addition it is the human resources sector that makes sure that there is a display of the details of the health and safety law that is displayed where everyone working in the store can in the store can see it.
