The average kinetic energy of a gas molecule can be determined by knowing

At constant volume,the pressure of a gas is directly proportional 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

If the average translational kinetic energy of a molecule in a gas is equal to the kinetic energy of an electron accelerating from rest through $10 \,V$, then the temperature of the gas molecule is (Boltzmann constant $= 1.38 \times 10^{-23} \,JK^{-1}$)

One kg of a diatomic gas is at a pressure of $8 \times 10^4 \ N/m^2$. The density of the gas is $4 \ kg/m^3$. What is the energy of the gas due to its thermal motion?

The relation between the gas pressure $P$ and average kinetic energy per unit volume $E$ is
