.(8) Problem: A Carnot cycle operates as a heat engine between two bodies of equal heat capacity until their temperatures become equal. If the initial temperatures ofthe bodies are 7, and 72, respectively, and 7, >T then their common final temperature is 7/7 (6) T/7 T +T7) Soln. Carnot cycle is reversible cycle so the entropy change must be zero.
