For a gas $\frac{R}{C_{v}}=0.4$  , where R is the universal gas constant and C_v is molar specific heat at constant volume. The gas is made up of  molecule which are

Answer:

Explanation:

According to question,

    $\frac{R}{C_{v}}=0.4$   

                   [R= universal gas constant and

C_v  = molar specific heat  at constant volume]

As we know, C_p-C_v  = R

So, $\frac{C_{p}-C_{v}}{C_{v}}=0.4\Rightarrow \frac{C_{p}}{C_{v}}=0.4+1=1.4$

 i.e, Y=1.4

 As Y=1.4, the gas is diatomic  in nature
