In which case will the efficiency of a Carnot cycle be higher, when the hot body temperature is increased by or when the cold body temperature is decreased by the same magnitude?
View answer and explanation
Correct option: B
On decreasing the temperature of cold body
Option B is correct because decreasing the cold body temperature has a greater impact on increasing the Carnot cycle efficiency.
