STANDARD Physics Adiabatic Processes MCQ Question
Type: MCQ-numerical-Medium-Class 11
A one mole of an ideal gas expands adiabatically at constant pressure such that its temperature T ∝ 1/√V. The value of the adiabatic constant of gas is
A
1.3
B
1.5
C
1.67
D
2.0
Correct Answer
Option B
Detailed Explanation
In an adiabatic expansion, PV^γ = constant. Given T ∝ 1/√V, we find γ by comparing with T ∝ V^(1-γ). Solving gives γ = 1.5.
