Question

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

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

Answer 1

Answer: (A)

Monoatomic

Answer 2

For a gas, we know $\frac{R}{C_{V}} = \gamma - 1$

or $0.67 = \gamma - 1or,\gamma = 1.67$

Hence the gas is monoatomic.
