The average kinetic energy of an ideal gas per molecule in $SI$ units at $25\,^oC$ will be

The correct plot of the Maxwell-Boltzmann distribution at different temperatures $(T)$ is:

What happens to the pressure if the collisions of gas molecules are not elastic?

According to the kinetic theory of gases,which of the following statements are correct?
$A$. Collisions are always elastic.
$B$. Heavier molecules transfer more momentum to the wall of the container.
$C$. Only a small number of molecules have very high velocity.
$D$. Between collisions,the molecules move in straight lines with constant velocities.

$A$ football bladder contains an equimolar mixture of $H_2$ and $O_2$. What is the ratio of the rate of diffusion of $H_2$ to $O_2$?

What kind of forces exist between the molecules in an ideal gas?
