Postulates of Kinetic Theory of Gases

If volume occupied by ${\mathrm{CO}}_2$​ molecules is negligible, then what will be the pressure $\left(\frac{P}{5.277}\right)$ exerted by one mole of at $27°\mathrm{C}$ is $\left(\mathrm{a}=3.592 {\mathrm{L}}^2 {\mathrm{mol}}^{-2}\right)$.

State the assumption regarding the volume of gas molecules to consider the gas as an ideal gas.

For gas to be ideal gas, it is assumed that the _____ of the molecules is negligibly small compared to the volume occupied by the gas.

The average kinetic energy of gas molecules does not depend upon temperature.

A gas diffuse $\frac{1}{5}$ times as fast as hydrogen. Its molecular weight is

The average kinetic energy of gas molecules does not depend upon temperature.

Assertion: According to kinetic theory of gases, all the collision between molecule-molecule, and between molecule-walls of container are perfectly elastic, so speed of each molecule in an isolated gaseous system remains constant.

Reason: Distribution of speed among the molecules of gas does not change with time for the above system.

Assertion: The potential energy of ideal gas is zero.

Reason: At low pressure or high temperature the molecules are far apart and molecular interactions are negligible.

A liquid is in equilibrium with its vapours at its boiling point. On the average, the molecules in the two phases have equal:

Different gases at the same temperature have same

What is the average velocities of particles in a gas

A container of volume $1 {\mathrm{m}}^3$ is divided into two equal compartments by a partition. One of these compartments contains and ideal gas at $300 \mathrm{K}$. The other compartment is vacuum. The whole system is thermally isolated from its surroundings. The partition is removed and the gas expands to occupy the whole volume of the container. Its temperature now would be
