A perfect Carnot engine operates between 350 K and 600 K. The engine delivers 10 kJ of work in each cycle. How much heat is extracted from the 600 K reservoir in one cycle?

Question

Quizplus · Accepted Answer

The efficiency of a Carnot engine is given by 1 - (T_cold/T_hot) = 1 - (350/600) = 0.4167. The work done is 10 kJ, so the heat extracted from the hot reservoir is Work / Efficiency = 10 kJ / 0.4167 ≈ 24 kJ.
