For problem 1 explain why the COP (which really means efficiency) should be calculated the way that it is, and why there is a maximum COP for this specific refrigerator in terms of entropy.
What is the best coefficient of performance possible for a
hypothetical refrigerator that could make liquid nitrogen at
−200ºC and has heat transfer to the environment at
35.0ºC ?

4. Refrigeration and air conditioning is quite useful, but it is, in effect, a way to move heat from a low temperature to a high temperature. Is this possible, given the second law? Answer the following questions below, for R-134a (a common refrigerant), and then state whether you believe refrigeration violates the second law, and why (or why not) a. R-134a arrives to the inside of the refrigerator that you are trying to keep cooled to T- 4°C. The air...

Fellco Manufacturing produces replacement parts for motorcycles.
They specialize in the production of Part 240 and Part 390. Part
240 is the highest volume of the two and for many years was the
only part the company produced. Four years ago, Part 390 was added.
Part 390 is much more difficult to manufacture and requires special
