WHAT IS DIFUTION
Diffusion, also called molecular diffusion, is the process by which molecules of a given substance move from an area of relatively high concentration to an area of lower concentration. When the molecules have diffused so that they are in a uniform concentration, this state is called equilibrium. This phenomenon plays a key role in many disciplines of biology, physics, and chemistry. It is closely related to the way in which cells take up nutrients, thus life could not exist without it.
