Vedclass · Answer

(B) We know that for an ideal gas,the relationship between the molar heat capacity at constant volume $(C_v)$,the universal gas constant $(R)$,and the adiabatic index $(\gamma)$ is given by Mayer's relation: $C_p - C_v = R$. Dividing by $C_v$,we get $\frac{C_p}{C_v} - 1 = \frac{R}{C_v}$. Since $\gamma = \frac{C_p}{C_v}$,we have $\gamma - 1 = \frac{R}{C_v}$. Given that $\frac{R}{C_v} = 0.4$,we substitute this into the equation: $\gamma - 1 = 0.4$,which gives $\gamma = 1.4$. $A$ value of $\gamma = 1.4$ corresponds to a diatomic gas.

For a gas,the value of $\frac{R}{C_v} = 0.4$. What is the nature of the gas? ($R$ is the universal gas constant)
