In the case of a diatomic gas,the fraction of heat supplied at constant pressure that is used for the expansion of the gas is:

In gases of diatomic molecules,the ratio of the two specific heats of gases ${C_P}/{C_V}$ is

The specific heat of helium at constant volume is $12.6 \,J \,mol^{-1} \,K^{-1}$. The specific heat of helium at constant pressure in $J \,mol^{-1} \,K^{-1}$ is approximately (assume, the universal gas constant, $R=8.314 \,J \,mol^{-1} \,K^{-1}$)

The specific heat of Argon at constant volume is $0.075 \ kcal/kg \ K$. The value of its atomic weight is..... [$R = 2 \ cal/mol \ K$]

To an ideal triatomic gas $800 \,cal$ heat energy is given at constant pressure. If vibrational mode is neglected,then energy used by gas in work done against surroundings is ......... $cal$.

For a gas,the difference between the two specific heats is $4150 \ J \ kg^{-1} \ K^{-1}$ and the ratio of the two specific heats is $1.4$. What is the specific heat of the gas at constant volume in units of $J \ kg^{-1} \ K^{-1}$?
