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

The correct relation between the degree of freedom $f$ and the ratio of specific heat $\gamma$ is

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 specific heat relation for an ideal gas is:

The following sets of values for ${C_V}$ and ${C_P}$ of a gas have been reported by different students. The units are $cal/gm-mole-K$. Which of these sets is most reliable?

The ratio of the molar specific heat capacities of monatomic and diatomic gases at constant pressure is (in $: 7$)
