Calculate the net work output of a heat engine following path \( A B C D A \) in the figure below. Hf Unreasonable Results What is wrong with the claim that a cyclical heat engine does \( 4.00 \mathrm{~kJ} \) of work on an input of \( 24.0 \mathrm{~kJ} \) of heat transfer while \( 16.0 \mathrm{~kJ} \) of heat transfers to the environment?
Expert Answer
For a cyclic process, work done can be calculated by area enclosed by the cycle in P-V diagram. In the given P-V diagram, the area enclosed is ABCDA,
