All reversible engines operating between the same two temperatures have the same efficiency.

Question

Quizplus · Accepted Answer

This statement is a restatement of the second law of thermodynamics, known as the Carnot's theorem, which states that no reversible engine can be more efficient than a Carnot engine operating between the same two temperatures. Therefore, all reversible engines operating between the same two temperatures have the same maximum efficiency, which is determined by the Carnot efficiency formula.
