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

The kinetic energy of $1 \ mol$ of an ideal gas is given by:

Liquids diffuse more slowly than gases because.....

The mass of molecule $A$ is half the mass of molecule $B$. The $rms$ speed of $A$ is twice the $rms$ speed of $B$. If two samples of $A$ and $B$ contain the same number of molecules and are taken in two separate containers of equal volume,what will be the ratio of the pressure of $A$ to the pressure of $B$ $(P_A/P_B)$?

The total kinetic energy $(KE)$ of $1 \ mol$ of a monoatomic ideal gas at $27 \ ^oC$ is ........ $cal$.

The energy of an ideal gas depends only on its
