Question: In a Carnot engine, if the hot reservoir is at 500 K and the cold reservoir is at 300 K, what is the maximum efficiency?

Options:

  1. 40%
  2. 60%
  3. 50%
  4. 20%

Correct Answer: 60%

Solution: 

The maximum efficiency of a Carnot engine is given by 1 - (T_c/T_h), which is 1 - (300/500) = 0.4 or 40%.
