Q. Our model of an ideal gas describes gases as a collection of small, rigid spheres, in constant, rapid motion. Because the molecules are very small compared to the space they occupy, we say the molecules have negligible volume. This means that molecules are more likely to collide with the container walls than they are to collide with each other.
Nonetheless, intermolecules collisions are possible and do occur. We refer to the distance a molecule can travel without hitting something else as its mean free path.
Which of the following change possibilities would INCREASE the mean free path of molecules is a sample of confined gas, assuming no change in the number of molecules in the system?

Q. The main reason for deviation of gases from ideal behaviour is few assumptions of kinetic theory. These are
(i) there is no force of attraction between the molecules of a gas
(ii) volume of the molecules of a gas is negligibly small in comparison to the volume of the gas
(iii) Particles of a gas are always in constant random motion.
