If the efficiency of a Carnot engine were to be $100 \%$, the heat sink would have to be
A) at $100 ^ { \circ } \mathrm { C }$.
B) at $0 ^ { \circ } \mathrm { C }$.
C) infinitely hot.
D) at absolute zero.

Question

Quizplus · Accepted Answer

For a Carnot engine to achieve 100% efficiency, the temperature of the heat sink would need to be at absolute zero. This is because the efficiency of a Carnot engine is determined by the temperatures of the heat source and the heat sink, and to achieve 100% efficiency, the temperature difference would need to be as large as possible, with the lower limit being absolute zero.
