What Is the Zeroth Law of Thermodynamics

The zeroth law of thermodynamics states that if two systems are both in thermal equilibrium with a third system, then the first two systems are also in thermal equilibrium with each other. Key Takeaways: Zeroth Law of Thermodynamics The zeroth law of thermodynamics is one of the four laws of thermodynamics, which states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with one another.Thermodynamics is the study of the relationship between heat, temperature, work, and energy.Most generally, equilibrium refers to a balanced state that does not change overall with time.Thermal equilibrium refers to the situation where two objects that can transfer heat to each other stay at a constant temperature over time. Understanding Thermodynamics Thermodynamics is the study of the relationship between heat, temperature, work—which is performed when a force applied to an object causes that object to move—and energy, which comes in many forms and is defined as the capacity to do work. The four laws of thermodynamics describe how the fundamental physical quantities of temperature, energy, and entropy change in various situations. As an example of thermodynamics in action, placing a pot of water on a heated stove will cause the pot to heat up because heat is transferred to the pot from the stove. This in turn causes the molecules of water to bounce around in the pot. The faster movement of these molecules is observed as hotter water. If the stove had not been hot, it would not have transferred any thermal energy to the pot; thus, the water molecules could not have begun moving faster and the pot of water would not have heated up. Thermodynamics emerged in the 19th century, when scientists were building and improving steam engines, which use steam to help move an object such as a train. Understanding Equilibrium Most generally, equilibrium refers to a balanced state that does not change overall with time. This does not mean that nothing is happening; rather, that two influences or forces are balancing each other out. Consider, for example, a weight hanging from a string attached to the ceiling. At first, the two are in equilibrium with one another and the string does not break. If more weight is attached to the string, however, the string will be tugged downward and may eventually break as the two are no longer in equilibrium. Thermal Equilibrium Thermal equilibrium refers to the situation where two objects that can transfer heat to each other stay at a constant temperature over time. Heat can be transferred several ways, including if the objects are in contact with one another or if heat is radiated from a source like a lamp or a sun. Two objects are not in thermal equilibrium if the overall temperature changes with time, but they can approach thermal equilibrium as the hotter object transfers heat to the colder one. Consider, for example, a colder object touching a hotter object—like ice that has been dropped in a hot cup of coffee. After some time, the ice (later water) and the coffee will reach a certain temperature that is in between that of the ice and the coffee. Though the two objects were not in thermal equilibrium at the beginning, they approach—and eventually reach—thermal equilibrium, the temperature in between the hot and cold temperatures. What Is the Zeroth Law of Thermodynamics? The zeroth law of thermodynamics is one of the four laws of thermodynamics, which states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with one another. As seen from the above section on thermal equilibrium, these three objects will approach the same temperature. Applications of the Zeroth Law of Thermodynamics The zeroth law of thermodynamics is seen in many everyday situations. The thermometer may be the most well-known example of the zeroth law in action. For example, say the thermostat in your bedroom reads 67 degrees Fahrenheit. This means that the thermostat is in thermal equilibrium with your bedroom. However, because of the zeroth law of the thermodynamics, you can assume that both the room and other objects in the room (say, a clock hanging in the wall) are also at 67 degrees Fahrenheit.Similar to the above example, if you take a glass of ice water and a glass of hot water and place them on the kitchen countertop for a few hours, they will eventually reach thermal equilibrium with the room, with all 3 reaching the same temperature.If you place a package of meat in your freezer and leave it overnight, you assume that the meat has reached the same temperature as the freezer and the other items in the freezer.

The Merry Wives of Windsor - Character Analysis

In The Merry Wives of Windsor, a character is a key ingredient that makes this play one of Shakespeare’s funniest comedies. This â€Å"who’s who† of characters is written to aid your study and enjoyment of the play. You can also find more detail on Sir John Falstaff and Mistress Quickly in these articles. Mistress Ford A resident of Windsor, Mistress Ford is married to Ford, who is a fiercely jealous husband. When Mistress Ford receives a letter from Falstaff trying to seduce her, she finds that her best friend Mistress Page has also received a similar letter. Mistress Ford is a strong independent woman and in the spirit of girl power, she and Mistress Page decide to teach the men in their lives a lesson. They decide to humiliate Falstaff who has attempted to disgrace them. Mistress Ford also sets out to prove to her husband for once and for all that she is a faithful and loyal wife. She is successful in her plans and outwits the male characters proving herself to be a loyal wife but not without teaching her husband and Falstaff a lesson...don’t try and cross her or doubt her, you will regret it. Mistress Page Mistress Page also lives in Windsor. She is married to Page and is the mother of Anne Page. Anne has attracted many suitors and Mistress Page and her husband disagree about who is most suitable for their daughter. She prefers Caius as a match for her daughter whereas her husband favors Slender. Anne likes neither of her parents’ choices and she teaches her mother and father a lesson at the end of the play by marrying her true love. Mistress Page and her husband are made to see that the most important thing was to listen to their daughter and find out who she preferred. Anne takes after her mother in many ways, she teaches them a lesson in the same way that her mother teaches Falstaff the error of his ways. Ford Ford is the jealous husband of Mistress Ford. Presumably, low self-esteem leads to him believing that Falstaff will succeed in seducing his wife, also a shameful lack of belief in his wife’s loyalty to him. Ford even decides to disguise himself as ‘Brooke’ to find out from Falstaff how his wife has been responding to his advances. Of course, Falstaff informs him that his wife has arranged to meet Falstaff secretly which enrages Ford further believing that his wife is being unfaithful. He eventually comes to understand the truth and gains more respect for his wife in that she orchestrates the humiliation and downfall of Falstaff and thus proving her loyalty to him as her husband. He is made to feel a little silly for not believing in her. Page Page is a much easier going character than Ford and does not believe that his wife will be seduced by Falstaff – this shows that he has faith in his wife and shows their relationship to be much more secure. However, he does not listen to his daughter about who she is in love with and is finally taught a lesson by her. Anne Page Anne is Mistress Page and Page’s daughter. She has an array of unworthy suitors including Caius and Slender who her parents favor but Anne is in love with Fenton. She eventually elopes with Fenton and turns up with him to show her parents up and demonstrate that true love is more important. Sir Hugh Evans Sir Hugh is a Welsh Clergyman and much merriment is made about his accent. Sir Hugh Evans and Caius finally group together to humiliate the Host who has made fools of them. Caius Mistress Quickly’s Master and the local Doctor. He is French and like Hugh Evans is mocked for his accent. He is in Love with Anne Page and Mistress Page approves of the match but her husband Page and Anne herself do not like Caius. Caius teams up with Evans to give the Host his comeuppance. Slender Another match for Anne Page. Urged on by Shallow, Slender tries to seduce Anne but is only able to talk nonsense to her. Slender is overlooked by Anne. Fenton Anne’s true love, Fenton is discounted by Page who believes he is after Anne’s money, which he admits he was at first but on getting to know Anne he has fallen in love with her. They elope in secret.

Essay about Technology and Education - 2965 Words

Technology and Education Introduction Can you imagine a classroom so technologically advanced that every student had access to flat-screen computers, palm pilots, high-tech laboratories, electronic toys, laptops, video games, on-line class sessions and help, chat rooms, and other emerging technologies? Wouldnt it be fun to learn in that type of an environment! Essentially, the purpose of this research paper is to explore and evaluate how public education effectively incorporates use of these and other advances in technology to meet classroom demands with innovative technique. I begin by examining how schools have used technology in the past in order to gain insight from where we have come. Secondly, I investigate how todays†¦show more content†¦While announcement and discussion boards vary from a traditional chalkboard in appearance and media, they still function much in the same way that a chalkboard does. Announcement and discussion boards provide information to the students using a visual display that the stu dents have unlimited access to. Announcement boards are online websites that function as a chat-room in which students are able to view information any time they want from any computer that has internet access. They are also able to communicate more effectively using the discussion board regardless if the class session has ended (CIAT brochure, 2002). Nevertheless, jumping ahead into the 1950’s and 60’s we now have the radio (1920’s), movies, and television, which drastically change the appearance of education (PBS, 2000). It is easy to comprehend how these devices have been integrated into the classroom and even outside of the classroom. Take, for example, the children’s television show Sesame Street, which is educational in nature. This show, which began in 1969, was created to teach preschoolers skills that would help them succeed in their early elementary years (anonymous, 2002). This is an excellent demonstration of an effectively integrated educatio nal tool into public education, even outside of the classroom.

Information Security and Risk Management

Question: Discuss about theInformation Security and Risk Management. Answer: Introduction As per the given scenario, Hillside Hospital is a 100 bed hospital and it provides various facilities to its patients such as emergency care, maternal and child health, chronic disease management with different specialists. Besides this, other facilities such as radiology, pharmacy, rehabilitation services are also provided by Hillside Hospital. For take care of patients, several healthcare providers are available in hospital such as specialist, registrars, medical officers, nurses and physiotherapist. It is also found that some of the staff members in the hospital are involved in medical research and clinical trial and for their research they need to use patients information from system. In this case, as a member of IT Expert Team, my team is concerned about management of security of information in hospitals environment. The sensitive information is stored into database, so it is necessary to maintain its security and privacy from unauthorized access of data. The purpose of making t his report is to design a security and risk management solution that can fulfill security requirements of hospital. The security and risk management plan will include Planning and Policy, Developing of Security Program, Risk Management and Protection Mechanism. Here in this report, we will discuss in detail planning and policy of security and risk management solution. Discussion The planning and policy of security and risk management solution should be effectively described so that it can be implemented effectively in hospital (Security Intelligence, 2017). Planning and Policy of Security and Risk Management Solution To protect information that is stored into hospitals database, we have made an effective plan that includes mission, vision, key components, policy, purpose, scope, information security requirements and policy details (Hinkel, 2017). Planning According to requirements of Hillside hospital for information security, we have planned to use security techniques such as cryptography to store encrypted data into database, implementation of strict security policies in hospitals, restricted access of database and periodic monitoring of database by administrator (Protectivesecurity.govt.nz, 2017). Mission The mission of Hillside hospital is to keep information with appropriate security and privacy with authorized access of data. It is matter of trust of people who have provided their information to store into hospitals database. Vision Hillside Hospital has vision to use advanced storage techniques in highly secure way to store huge amount of information. Besides this, hospital also wants to control security and privacy issues of information system at large extent by using advanced security tools and techniques (Nttsecurity.com, 2017). Key Components The key components of security and risk management solution are listed as below: Identification of assets that need to be protected such as customers information, critical business processes etc. and why protection is necessary of these assets? Identification of major threats to assets and what could happen with identified assets. Rank the identified threats by both probability and their impacts. Identify what types of controls will be suitable for protecting assets. Testing of accuracy and effectiveness of controls Proper monitoring of all process periodically (Securitymagazine.com, 2017). Policy The main policy that we would like to implement in Hillside hospital for information security is that system administrator must set unique login credentials for hospital employees for accessing database and different permissions should be accessed to all according to their post in hospital. Purpose The purpose of making above policy and planning is to enhance security level of hospitals database as much as possible by using modern intelligent security tools and techniques and it is also necessary to get protection from hacking attacks. Scope The scope of this planning and policy is wide because proper implementation of these policies will help every business organization, hospitals and other individuals to make their information secured for long time. Information Security Requirements The main requirements of information security are identification of issues of hospital that are affecting information security, proper organization of security policies and standards, train all employees to implement information security policies and standards and implementation of information security standards. Policy Details As we have provided a brief information about security policy for Hillside Hospital, here is detail about that policy. According to that policy by setting different login credentials for different level employees, low level employees will not have permission to access most sensitive information about top level staff members. This policy will reduce chances of leaking information. Besides this, every activity of employees on their computers while accessing information should be detected by using detection control systems. These systems have some advanced features such as if an employee will try to access unauthorized information from database from his computer then it will send message to administrator.
