Question and answer
What is the thermal efficiency of an imaginary ideal gas engine
To find the thermal efficiency of an ideal engine, examine the entropy changes that take place during one cycle. [ Because all the processes are reversible, the net entropy change per cycle for the entire closed system (the working substance of the engine plus the high- and low-temperature reservoirs) must be zero. The entropy change of the working substance is zero because the substance returns to its initial state at the end of each cycle. Thus the magnitude of the entropy decrease of the high-temperature reservoir must equal the magnitude of the entropy decrease of the low-temperature
reservoir. ]
