STANDARD Physics Specific Heat Capacities of Gases MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The value of γ (Cₚ/Cᵥ), for hydrogen, helium and another ideal diatomic gas X (whose molecules are not rigid but have an additional vibrational mode), are respectively equal to
A
7/5, 9/5, 3/7
B
5/3, 7/5, 9/7
C
5/3, 7/5, 7/5
D
7/5, 5/3, 7/5
Correct Answer
Option B
Detailed Explanation
For H₂, γ = 1 + 2/5 = 7/5; For He, γ = 1 + 2/3 = 5/3; For X, γ = 1 + 2/7 = 9/7.
