If the temperature increases from $20\,^oC$ to $40\,^oC$,by what factor does the average kinetic energy of neon atoms change?

For a gas,the ratio $C_p/C_v$ is $1.3$ and its atomic mass is $M$. What is the molecular mass of the gas?

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.

When the temperature of a neon atom is increased from $20\,^oC$ to $40\,^oC$,by what factor does its average kinetic energy change?

The kinetic energy of $4 \ mol$ of $N_2$ gas at $127 \ ^oC$ is ............. $cal$.

Assertion : Gases do not settle to the bottom of a container.
Reason : Gases have high kinetic energy.
