Two heat engines

A

and

B

have their sources at 1000 K and 1100 K and their sinks are at 500 K and 400 K respectively. What is true about their efficiencies?

View answer and explanation

Correct option: C

{\eta _A} < {\eta _B}

Option C (

{\eta _A} < {\eta _B}

) is correct because the efficiency of a heat engine depends on the temperatures of the source and sink, and engine B has a higher efficiency.
