B)For all reversible processes, the second-law efficiency is 100%.
C)The thermal efficiency of a heat engine cannot be greater than its second-law efficiency.
D)The second-law efficiency of a process is 100% if no entropy is generated during that process.
E)The coefficient of performance of a heat pump can be greater than 1.

Question

Quizplus · Accepted Answer

The thermal efficiency of all reversible heat engines is not 100%; it is determined by the Carnot efficiency, which depends on the temperatures of the heat reservoirs.
