Question

If for a gas $\frac{R}{C_V}=0.67$, this gas is made up of molecules which are.

• A. Monatomic
• B. Diatomic
• C. Polyatomic
• D. Mixture of diatomic and polyatomic molecules

Answer 1

Answer: (A)

Monatomic

For a gas, we know $\frac{R}{C_V}=\gamma -1$
or $0.67=\gamma -1$ or, $\gamma =1.67$
Hence the gas is monatomic.
