A heat engine is operating in between 600 K and 450 K. If the engine absorbs 200 J heat per cycle, then which of the following is/are impossible amount(s) of heat rejected by the engine per cycle?
Options:(select one or more)
Answer:
B, D
Solution:
The maximum (Carnot) efficiency is 1 - 450/600 = 0.25, so the work is at most 50 J and the heat rejected is at least 200 - 50 = 150 J. Rejecting 145 J or 100 J would beat the Carnot limit. 165 J and 180 J are possible. Ans: (b), (d).
