JEE Main 2025 Physics question
is the specific heat ratio of monoatomic gas A having 3 translational degrees of freedom. is the specific heat ratio of polyatomic gas B having 3 translational, 3 rotational degrees of freedom and 1 vibrational mode. If , then the value of n is .
Answer: 3
Solution
γA=5/3, fB=8 (vibrational mode contributes 2), γB=5/4. γA/γB=4/3=1+1/3, n=3.
