The average $K.E.$ of an ideal gas in calories per mole is approximately equal to

At a temperature of $300 \ K$,which of the following has higher kinetic energy: $N_2$ or $O_2$?

What is the temperature at which the kinetic energy of $0.3 \ mol$ of helium is equal to the kinetic energy of $0.4 \ mol$ of argon at $400 \ K$ (in $K$)?

What is an elastic molecular collision?

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

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 $B$ $(P_A/P_B)$?
