Answer:
Efficiency of heat engine: The efficiency of a heat engine is defined as the ratio of the net work done by the engine in one cycle to the amount of heat absorbed by the working substance from the source. Efficiency of a heat engine is always less than unity. Clearly, when Q2 = 0, η= 1 or 100%.
