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.
The rate of flow of energy or particles across a given surface.
