Vedclass · Answer

(A) The average kinetic energy $(K_{avg})$ of a gas molecule is given by the formula: $K_{avg} = \frac{3}{2} k_B T$,where $k_B$ is the Boltzmann constant and $T$ is the absolute temperature.From this formula,it is clear that the average kinetic energy depends only on the absolute temperature $T$ and is independent of the mass or nature of the gas molecule.Given that the average kinetic energy of $H_2$ molecules at $300 \ K$ is $E$,and since the temperature for $O_2$ molecules is also $300 \ K$,the average kinetic energy of $O_2$ molecules will also be $E$.

The average kinetic energy of $H_2$ molecules at $300 \ K$ is $E$. At the same temperature,the average kinetic energy of an $O_2$ molecule is:
