The molar specific heat at constant pressure for a monoatomic gas is

The difference between the two specific heats of $1\, g$ of helium gas at $NTP$ is .... $cal\, g^{-1} K^{-1}$. (Atomic weight of helium $= 4$ and $J = 4.186 \times 10^7\, erg\, cal^{-1}$)

What will be the molar specific heat at constant volume of an ideal gas consisting of rigid diatomic molecules?

If the molar specific heat at constant volume is $\frac{3R}{2}$,then the adiabatic index $\gamma$ is:

For a gas,the difference between the two specific heats is $4150 \ J/kg \ K$. What is the specific heat at constant volume of the gas if the ratio of specific heats is $1.4$ (in $J/kg \ K$)?

For a gas,$\frac{R}{C_{v}} = 0.67$. This gas is made up of molecules which are
