Increase in temperature of a gas filled in a container would lead to

The average kinetic energy of hydrogen molecules at $300\, K$ is $E$. At the same temperature,the average kinetic energy of oxygen molecules will be

We sit in a room with windows open. Then,

$A$ vessel of volume $10 \text{ liters}$ is filled with $H_2$ gas. The total average translational kinetic energy of its molecules is $4.5 \times 10^5 \text{ J}$. The pressure of hydrogen in the vessel is

At absolute zero temperature,the kinetic energy of the molecules

At which of the following temperatures would the molecules of a gas have twice the average kinetic energy they have at $20^{\circ}C$ (in $^{\circ}C$)?
