Q. The average translational kinetic energy of $O_{2}$ (molar mass $32$ ) molecules at a particular temperature is $0.048\,eV$ . The translational kinetic energy of $N_{2}$ (molar mass $28$ ) molecules in $eV$ ,at the same temperature is

Solution:

Given that,
$E_{O_{2}}=0.048\,eV$ .
We know that, $E=\frac{3}{2}kT\,$ .
Since, $k\,$ is constant and according to the question, $T\,$ is also constant.
Thus, $E_{N_{2}}=0.048\,eV$ .
As The average translational kinetic energy depends on temperature only.
