A heat engine operates between T_c = 294 K and T_h = 450 K.What is the maximum possible efficiency? A)0.35 B)0.65 C)0.53 D)1.53

Question

Quizplus · Accepted Answer

The maximum possible efficiency of a heat engine is given by the Carnot efficiency, which is:η_C = 1 - T_c / T_hwhere T_c is the temperature of the cold reservoir and T_h is the temperature of the hot reservoir.In this case, T_c = 294 K and T_h = 450 K, so the maximum possible efficiency is:η_C = 1 - 294 K / 450 K = 0.35Therefore, the correct answer is A.

A Heat Engine Operates Between Tc = 294 K and Th
