The ratio of the adiabatic to isothermal elasticities of a triatomic (non-linear) gas is
- A \(3: 4\)
- B \(1: 2\)
- C \(4: 3\)
- D \(5: 3\)
Answer & Solution
Correct Answer
(C) \(4: 3\)
Step-by-step Solution
Detailed explanation
For triatomic non-linear gas degree of freedom, \(f=6\) \(\begin{aligned} & C_V=\frac{f R}{2}=\frac{6 R}{2}=3 R \\ \therefore \quad C_p & =C_V+R=3 R+R=4 R \end{aligned}\) \(\therefore\) Ratio of adiabatic to isothermal elasticities of a triatomic (non-linear) gas is…
