DIFFDiffusion of Chemicals * Diffusion-is the process whereby particles of liquids‚ gases‚ or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration. The rate of diffusion depends on the size of the surface area to the volume in the cell. The higher the surface area of cells in relation to their volume‚ the quicker diffusion takes place.
