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?

(c) How much heat does it give off in each cycle?

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