STANDARD Physics Cyclic Processes MCQ Question
Type: MCQ-numerical-Medium-Class 11
An ideal gas undergoes cyclic process ABCDA as shown in given P-V diagram. The amount of work done by the gas is
A
6P₀V₀
B
−2P₀V₀
C
+2P₀V₀
D
+4P₀V₀
Correct Answer
Option B
Detailed Explanation
Work done = area ABCDA = change in pressure × change in volume = (2P₀ − P₀) (3V₀ − V₀) = 2P₀V₀. Since the cyclic process is anticlockwise, work done by the gas is negative, i.e., −2P₀V₀.
