Take a look around yourself. What do you see? Maybe books, chairs, a television, or even your clothes. All the day to day things that are man-made, you can be sure that an engineer helped make it. Engineers have shaped our world as we know it. There are many different kinds of engineers from chemical, mechanical, textile, civil, agricultural and structural engineers. Our civilization would be as advanced as the Stone Age without these people. This career demands a wide education of math and science. It is an ever-changing career with new advances in materials and the way products are produced. Engineering careers are very secure with respect to compensation. Regardless of this, it does have it’s disadvantages…show more content…
(Britannica 243) Another disadvantage of being an engineer is the actual status of being one. It is not looked upon as highly as other fields such as doctors and lawyers. Most of the time they are looked upon as nerds. In addition, most engineers are not promoted to high level positions such as presidents or top executives. They do not have the accounting or business education to do that particular job. This means that most engineers never get the opportunity to be their own boss. (Basta 22)
The job of an engineer itself is a creative job. The actual definition of an engineer is “The profession in which a knowledge of the mathematical and natural sciences gained by study, experience and practice is applied with judgment to develop ways to utilize the materials and forces of nature economically for the benefit of mankind.” (Bastas 24) In having the basic skills and experiences in math and science, an engineer is basically an inventor. They are given a problem and are depended on to come up with a solution. Whether it be a new chemical, a mechanical part, or even a whole new system such as computer operating program, engineers are the problem solvers of our materialistic society.

Why does the compression-refrigeration cycle have a high-pressure side and a low-pressure side?
a.The pressure difference is the result of polar molecular alignment due to the intense magnetic field created by the compressor motor.
b.So the refrigerant can condense at a low pressure and temperature and evaporate at a high pressure and temperature
c.The pressure difference isn't intentionally created but is simply the result of circulating refrigerant within the compressor.
d.So the refrigerant can evaporate at a low pressure and temperature and condense at a high pressure and temperature
Answer: D
Explanation:
The refrigerant can evaporate at low pressure and temperature and condense at high pressure and temperature. The correct option is D.
What is the Vapor compression cycle?The vapor compression cycle is a refrigeration cycle in which the heat is extracted from one place and is transferred to the atmosphere to cool the specified place.
Refrigeration is the process of keeping the temperature of the required place lower than that of the atmosphere by using different refrigeration processes like vapor compression, and vapor absorption processes.
In the vapor compression refrigeration cycle the refrigerant is evaporated at low pressure and temperature and condensed at high pressure and temperature.
The vapors of refrigerants are formed by taking the heat now these vapors are compressed in the compressor at a higher temperature and pressure than that of the atmosphere so that heat can be transferred to the atmosphere.
