At what temperature will the total kinetic energy of $0.30 \ mol$ of $He$ be the same as the total kinetic energy of $0.40 \ mol$ of $Ar$ at $400 \ K$ (in $K$)?

Explain the microscopic model of gases.

According to the kinetic molecular theory of gases,which of the following statements are correct?
$a$) The actual volume of the molecules is negligible in comparison to the empty space between them.
$b$) Collisions of gas molecules are inelastic.
$c$) At any particular time,different particles in the gas have the same speed and same kinetic energies.
$d$) Pressure is exerted by the gas as a result of the collision of the particles with the walls of the container.

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