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.
osmosis Osmosis is a special example of diffusion. It is the diffusion of a substance through a semipermeable membrane from a more dilute solution to a more concentrated solution. This process is also passive since no external energy is needed. A semipermeable membrane is a barrier that permits the passage of some substances but not others.
