Question

A thermodynamic system, undergoes cyclic process ABCDA as shown in figure. The work done by the system in the cycle is

(a) P₀V₀

(b) 2p₀V₀

(c) P₀V_0^/2

(d)  zero

Answer 1

Correct option (d)  zero

Explanation:

In a cyclic process work done is equal to the area under the cycle and is positive if the cycle is clockwise and negative if anticlockwise. As is clear from figure,
