absorption

absorption [Lat.,=sucking from], taking of molecules of one substance directly into another substance. It is contrasted with adsorption , in which the molecules adhere only to the surface of the second substance. Absorption may be either a physical or a chemical process, physical absorption involving such factors as solubility and vapor-pressure relationships and chemical absorption involving chemical reactions between the absorbed substance and the absorbing medium.
