What is the molar heat capacity of water? ($R$ is the universal gas constant.)

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 ......... $cal$.

The ratio of the specific heats $\frac{C_p}{C_v} = \gamma$ in terms of degrees of freedom $(n)$ is given by

For an ideal non-rigid diatomic gas,the value of $\frac{R}{C_V}$ is nearly,given that $\gamma = \frac{C_P}{C_V} = \frac{9}{7}$.

If the specific heats of a monoatomic gas and a diatomic gas are the same, which relation is valid?

To increase the temperature of $1$ $mol$ of an ideal gas by $10$ $K$ at constant pressure,$207$ $J$ of heat is required. If the temperature of this gas is increased by $10$ $K$ at constant volume,the heat required is ....... $J$ $(R = 8.3$ $J/mol$ $K)$.
