Home » Thermal Physics » Thermodynamics » Question

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

1. P₀V₀
2. 2 P₀V₀
3. P₀V₀
  2
4. Zero

Correct Option: D

Work done by the system in the cycle = Area under P-V curve and V-axis

=	1	(2P₀ - P₀)(2V₀ - V₀)		-		1		(3P₀ - 2P₀)(2V₀ - V₀)
	2					2

=	P₀V₀	-	P₀V₀	= 0
	2		2
