JEE · NEET Previous Year Question

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

Topic: JEE PYQ

Answer: A. Full step-by-step solution below.

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

Correct answer: A

Solution

(a) For a gas, we know \frac{R}{C _{V}} = γ - 1 or 0.67 = γ - 1 or, γ = 1.67 Hence the gas is monoatomic.
