Question: What is the maximum efficiency of a Carnot engine operating between two heat reservoirs at temperatures T_H and T_C?
Options:
Correct Answer: 1 - T_C/T_H
Solution:
The efficiency of a Carnot engine is given by the formula η = 1 - (T_C/T_H), where T_H is the temperature of the hot reservoir and T_C is the temperature of the cold reservoir.
