At very high temperatures, a diatomic gas behaves like a rigid rotator with five degrees of freedom. If the temperature is increased further, what happens to the specific heat at constant volume ($C_v$)?

The root mean square speed of molecules of a gas is 1260 m/s. The average speed of the gas molecules is

The temperature of argon, kept in a vessel, is raised by ${1^ \circ }C$ at a constant volume. The total heat supplied to the gas is a combination of translation and rotational energies. Their respective shares are

A gas mixture consists of 2 moles of $O_2$ and 4 moles of $Ar$ at temperature $T$. If the vibrational modes are negligible, what is the total internal energy of the system?

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

The ratio of specific heats (γ) for a monoatomic ideal gas is:

A cylinder rolls without slipping down an inclined plane, the number of degrees of freedom it has, is

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

Two moles of monoatomic gas is mixed with three moles of a diatomic gas. The molar specific heat of the mixture at constant volume is

The temperature of argon, kept in a vessel, is raised by ${1^ \circ }C$ at a constant volume. The total heat supplied to the gas is a combination of translation and rotational energies. Their respective shares are

The work of $146\,\,KJ$ is performed in order to compress one kilo mole of a gas adiabatically and in this process. The temp of the gas increases by $- {7^0}C$. The gas is $= 8.3\,\,J\,mo{l^{ - 1}}\,\,{K^{ - 1}}$
