Question:

A Carnot engine works between two heat reservoirs at temperatures Th = 300 K and Tc = 200K.

(a) What is its efficiency?

(b) If it absorbs 100 J from the hot reservoir during each cycle, how much work does it do?

(d) What is the coefficient of performance of this engine when it works as a refrigerator between these two reservoirs?
