When a system returns back to its initial state after passing by dissimilar phase, the phenomena is said to be a cyclic process. In this process as ΔU = 0.
From first law of thermodynamics,ΔQ = W
Thus in a cyclic phenomena, the heat absorbed by the system is equivalent to the net work done by the object. Work done is the area of the cycle on the PV diagram.
