A mixture of two ideal diatomic gases A and B, initially at temperatures $T_A$ and $T_B$ respectively, is allowed to reach thermal equilibrium at constant volume. If $n_A$ and $n_B$ are the number of moles of A and B, what is the final equilibrium temperature?

One mole of an ideal monatomic gas undergoes a process described by the equation $PV^3 = ext{constant}$. The heat capacity of the gas during this process is:

The gases carbon-monoxide (CO) and nitrogen at the same temperature have kinetic energies ${E_1}\;{\rm{and}}\;{E_2}$ respectively. Then

Considering the gases to be ideal, the value of $\gamma = \frac{{{C_P}}}{{{C_V}}}$ for a gaseous mixture consisting of 3 moles of carbon dioxide and 2 moles of oxygen will be $\left( {{\gamma _{{O_2}}} = 1.4,\;{\gamma _{C{O_2}}} = 1.3} \right)$

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 ${{\rm{O}}_2}$ and 4 moles of $Ar$ at temperature $T$. Neglecting all vibrational modes, the total internal energy of the system is

The molar specific heats of an ideal gas at constant pressure and volume are denoted by ${C_P}\,and\,{C_V}$ , respectively. If $\gamma = \frac{{{C_P}}}{{{C_{\;v}}}}$ and R is the universal gas constant. Then ${C_V}$ is equal to

A mixture of two ideal diatomic gases A and B, initially at temperatures $T_A$ and $T_B$ respectively, is allowed to reach thermal equilibrium at constant volume. If $n_A$ and $n_B$ are the number of moles of A and B, what is the final equilibrium temperature?
