State the relationship between kinetic energy and temperature for an ideal gas.

The diffusion coefficient of an ideal gas is proportional to its mean free path and mean speed. The absolute temperature of an ideal gas is increased $4$ times and its pressure is increased $2$ times. As a result,the diffusion coefficient of this gas increases $x$ times. The value of $x$ is

The volume occupied by $1$ mole of water vapor molecules at $STP$ is ..... (i.e.,Avogadro number $\times$ volume of one molecule).

$A$ $20 \ dm^3$ volume of $SO_2$ diffuses through a porous partition in $20 \ s$. What volume of $O_2$ gas in $dm^3$ will diffuse under the same conditions in $30 \ s$?

What is the internal energy of one mole of an ideal gas?

For a fixed number of moles of a gas at constant volume,the pressure of the gas increases with a rise in temperature due to:
