EXPERIMENT 1: ISENTROPIC EXPANSION PROCESS Objectives: 1) To demonstrate the isentropic expansion process. Introduction: In thermodynamics‚ an isentropic process is a process in which the process takes place from initiation to completion without an increase or decrease in the entropy of the system. One example of a process that approaches being isentropic are the rapid depressurization of gas in a cylinder. The entropy of the system remains in constant. Entropy is a type of energy

Thermal Expansion and Contraction Most of the matters‚ without some exceptions‚ expand with the increasing temperature. When you give heat to matters; speed of its particles increase and distance between them also increase which results in the increase of the volumes of matters. All expansions occurs in volume of the substance however‚ sometimes some of the dimensions of them expand more with respect to others. In this case we neglect the less expanded ones and assume expansion like linear expansion

Linear Thermal Expansion The term thermal expansion refers to the increase in size of an object as that object is heated. With relatively few exceptions‚ all objects expand when they are heated and contract when they are cooled. Perhaps the most important exception to this rule is water. Water contracts as it cools from its boiling point to about 39.2°F (4°C). At that point‚ it begins to expand as it cools further to its freezing point. This unusual effect explains the fact that ice is less dense

Spanish settlement of the west International borders has always been centers of conflict‚ and the U.S.-Mexican border is no exception. With the European colonizing the New World‚ it was a matter of time before the powers collided. The Spanish settled what is today Mexico‚ while the English settled what is today the United States. When the two colonial powers did meet became what is today the United States ’ Southwest‚ it was not England and Spain. Rather the two powers were the United States and

Westward Expansion. Although Manifest Destiny benefited the United States‚ it harmed the Native Americans. Due to Manifest Destiny and the Westward expansion‚ the Native Americans were stripped of their land and culture. One of the main things Native Americans didn’t like about the westward expansion was the fact that they had to move. This didn’t only anger the Native Americans but it had a large impact on their culture. In the book‚ “American History:

Global Expansion of McDonalds Many American corporations have attempted to expand their business globally. Some of these corporations have succeeded‚ but some have also failed because they have encountered different cultural barriers and differences that made it hard for these corporations to succeed. One of those multinational corporations that have encountered a few cultural barriers as they began global expansion was none other than McDonald’s. Though McDonald’s has encountered

Many factors lead to the beginning of the African exodus of the modern human population. The most prominent factors involved with their rapid expansion are the drastic climate changes in that area. As well as that‚ a diverse diet rich in seafood

The Westward Expansion was the acquisition of land out west from the Atlantic Ocean to the Pacific Ocean. During this expansion many changes occurred‚ some good and some bad. The changes could be grouped into three different categories‚ social‚ political‚ and economic. During westward expansion new changes‚ inventions‚ and ideas were quite common. One of these ideas was the telegraph wire. This wire allowed for people to communicate from far away places. During this time Manifest Destiny (The belief
