A nonlinear triatomic molecule has $N$ atoms. How many degrees of freedom for vibration does it possess?

A monoatomic ideal gas has how many degrees of freedom?

Two moles of oxygen is mixed with eight moles of helium. The effective specific heat of the mixture at constant volume is

One mole of a monoatomic ideal gas is mixed with one mole of a diatomic ideal gas. The molar specific heat of the mixture at constant volume is

What is the value of $\frac{R}{{{C_P}}}$ for diatomic gas

A gaseous mixture contains equal number of hydrogen and nitrogen molecules. Specific heat measurements on this mixture at temperatures below $100\;K$ would indicate that the of $\gamma$ (ratio specific heats) for this mixture is

For a gas if $\gamma = 1.4,$ then atomicity, ${C_P}$ and ${C_V}$ of the gas are respectively

Two closed containers hold different ideal gases at identical temperatures. If the pressure of the first gas is half the pressure of the second gas, and the density of the first gas is one-third the density of the second gas, what is the ratio of the molecular weight of the first gas to the second gas?

The ratio of the molar heat capacities of a diatomic gas at constant pressure to that at constant volume is

The specific heat at constant volume for a monoatomic ideal gas is given by:

A gas mixture consists of 2 moles of oxygen and 4 moles of argon at temperature $T$. Neglecting all vibrational moles, the total internal energy of the system is
