What Is Simple Diffusion? In a solution or gas that has an area of high numbers of particles and an area of lower numbers of particles, the particles will diffuse, or move, from the area of higher to the area of lower concentration.

Random motion is defined as movement that occurs by chance because there is no order or regular system by which the movements of the particles shift in a solution or gas.
