If for a gas, (R)/(CV)=0.67, the gas is...

If for a gas, `(R)/(C_V)=0.67`, the gas is

A

monatomic

B

diatomic

C

polyatomic

D

mixture of aiatomic and polyatomic molecules

Text Solution

Verified by Experts

The correct Answer is:
A
For a gas, we know `(R)/(V_(V))=gamma-1` ltbgt `or 0.67=gamma-1or,gamma=1.67`
Hence the gas is monatiomic.
