The average kinetic energy of \(\mathrm{H}_2\) molecules at \(300 \mathrm{~K}\) is \(E\). At the same temperature the average kinetic energy of \(\mathrm{O}_2\) molecule is
  1. \(E\)
  2. \(\frac{E}{4}\)
  3. \(\frac{E}{16}\)
  4. \(16 E\)

Solution

Average kinetic energy of \(\mathrm{H}_2\) molecules at \(\begin{aligned} 300 \mathrm{~K} & =E \\ E & \propto T \end{aligned}\) Since, Hence, at same temperature average kinetic energy of \(\mathrm{O}_2\) molecule will be same as \(E\).
