STANDARD Physics Heat Capacity MCQ Question
Type: MCQ-conceptual-Medium-Class 11
One mole of an ideal monoatomic gas undergoes a process described by the equation PV³ = constant. The heat capacity of the gas during this process is
A
3/2 R
B
5/2 R
C
2R
D
R
Correct Answer
Option D
Detailed Explanation
For a polytropic process, PV^α = constant. The heat capacity C = Cᵥ + (R/(1-α)). Given α = 3, C = R.
