An ideal Carnot engine extracts 529 J of heat from a high-temperature reservoir during each cycle, and rejects 225 J of heat to a low-temperature reservoir during the same cycle. What is the
Efficiency of the engine?
A) 0.7
B) 1.35
C) 2.35
D) 0.57

Question

Quizplus · Accepted Answer

The efficiency of a Carnot engine is given by the formula: Efficiency = 1 - (Qc/Qh), where Qc is the heat rejected and Qh is the heat absorbed. Here, Efficiency = 1 - (225/529) = 0.57.
