At $T(K)$,the $u_{rms}$ of $CO_2$ is $412 \ ms^{-1}$. What is its kinetic energy (in $kJ \ mol^{-1}$) at the same temperature? $(CO_2 = 44 \ u)$.

The average kinetic energy of one molecule of an ideal gas at $27^{\circ} C$ and $1 \ atm$ pressure is

The total kinetic energy of $0.6 \ mol$ of an ideal gas at $27 \ ^oC$ is .......... $J$.

If a gas expands at constant temperature,it indicates that

At $T$ $K$, the ratio of kinetic energies of $4$ $g$ of $H_{2(g)}$ and $8$ $g$ of $O_{2(g)}$ is
