STANDARD Physics Cyclic Processes MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A thermodynamical system undergoes cyclic process ABCDA as shown in figure. Work done by the system is
A
zero
B
2P₀V₀
C
P₀V₀
D
3/2 P₀V₀
Correct Answer
Option A
Detailed Explanation
The work done by the system in a cyclic process is equal to the area enclosed by the cycle on the PV diagram. In this case, the net work done is zero because the areas of the triangles ΔBCO and ΔAOD cancel each other out.
