The formula for mean free path (l) depends on the properties of the particles and the medium in which they are moving. In general, the formula for mean free path can be expressed as: l = 1/(√2 * π * d 2 * n) where: d is the diameter of the particles; n is the number density of particles in the medium

WebFor an ideal gas the heat transfer rate is proportional to the average molecular velocity, the mean free path, and the molar heat capacity of the gas. For non-metallic solids, the heat transfer is view as being transferred via lattice vibrations, as atoms vibrating more energetically at one part of a solid transfer that energy to less energetic ... In physics, mean free path is the average distance over which a moving particle (such as an atom, a molecule, or a photon) travels before substantially changing its direction or energy (or, in a specific context, other properties), typically as a result of one or more successive collisions with other particles.
