Question
Can you help with subparts a-c
5. A Carnot engine works between two heat reservoirs at temperatures Thot= 301.0 K and Tcold= 220.0 K.
a. What is its efficiency?
b. If it absorbs 200.0 J from the hot reservoir during each cycle, how much work does it do per cycle?
c. How much heat does it reject during each cycle?
d. What is the coefficient of performace, COP, of this engine when it works as a refrigerator between the same two reservoirs?
