The mean free path (λ) of a gas molecule is the average distance traveled by a molecule between two successive collisions. It is defined by:
λ = (k_B T) / (√2 π d² P)
where:
– k_B is Boltzmann’s constant,
– T is the temperature,
– d is the diameter of the molecule,
– P is the pressure.
Thus, the mean free path is the average distance traveled before a collision takes place.
The Maxwell-Boltzmann distribution gives the statistical distribution of molecular speeds in a gas at a given temperature.

The Maxwell-Boltzmann distribution gives the statistical distribution of molecular speeds in a gas at a given temperature. It is defined as:
f(v) = (m / 2πk_B T)^(3/2) * 4πv² * exp(-mv² / 2k_B T)

The kinetic theory of gases states that the temperature T of an ideal gas is proportional to the average kinetic energy per molecule, and it is represented as:
KE_avg = (3/2) k_B T
