As the temperature is raised from $20\,^{\circ}C$ to $40\,^{\circ}C$,the average kinetic energy of neon atoms changes by a factor of which of the following?

In a closed vessel,water exists in its three states: solid,liquid,and vapor at $0\,^oC$. In this condition,the average kinetic energy of water molecules will be ....

The kinetic theory of gases predicts that the total kinetic energy of a gaseous assembly depends on

The average kinetic energy of an ideal gas per molecule in $SI$ units at $25\,^oC$ will be

The diffusion coefficient of an ideal gas is proportional to its mean free path and mean speed. The absolute temperature of an ideal gas is increased $4$ times and its pressure is increased $2$ times. As a result,the diffusion coefficient of this gas increases $x$ times. The value of $x$ is

The kinetic energy of $4 \ mol$ of $N_2$ gas at $127 \ ^oC$ is ............. $cal$.
