For a gas `(R//C_(v))` = 0.67, the gas is made up of molecules which are

A

Diatomic

B

Mixture of diatomic and polyatomic molecules

C

Monoatomic

D

Pollyatomic

Text Solution

Verified by Experts

The correct Answer is:
C
`C_V=(R)/(0.67) implies C_V=1.49 R ~~ 1.5R=3/2 R`
Hence, f=3 (monoatomic gases).
