The kinetic energy of $2 \, \text{moles}$ of $N_2$ gas at $27 \, ^oC$ is .............. $J$.

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 $B$ $(P_A/P_B)$?

If a gas expands at a constant temperature,then...

The energy of an ideal gas depends only on its

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?

If a gas expands at constant temperature,it indicates that
