The translatory kinetic energy of a gas per $gm$ is

At $27^{\circ} C$ temperature,the mean kinetic energy of the atoms of an ideal gas is $E_1$. If the temperature is increased to $327^{\circ} C$,then the mean kinetic energy of the atoms will be

The average kinetic energy of a gas molecule at $27^oC$ is $6.21 \times 10^{-21} \, J$. Its average kinetic energy at $227^oC$ will be

The translational kinetic energy of the molecules of a gas at absolute temperature $T$ can be doubled by

The kinetic energy of $1$ mole of $He$ gas at $27^{\circ}C$ is .... $J$.

Consider a gas with density $\rho$ and $\bar{c}$ as the root mean square velocity of its molecules contained in a volume. If the system moves as a whole with velocity $v$,then the pressure exerted by the gas is
