Diffusion is a process leading to equalization of substance concentrations in a system or establishing in a system an equilibrium concentration distribution that results from random migration of the system's elements. Three types of diffusion are distinguished, viz., molecular, Brownian, and turbulent.
the mutual penetration of adjoining substances because of the thermal motion of their particles. Diffusion occurs in the direction of decreasing concentration of a substance and leads to a uniform distribution of matter over the entire volume it occupies (to the equalization of the chemical potential of matter).
