But, while absorption is a bulk phenomenon, i.e., occurs throughout a material, adsorption is limited only to the surface of a material.<\/p>\n<p>We use the word \u2018absorption\u2019 quite often in general communication, but \u2018adsorption\u2019, being a scientific term, is hardly used outside the academic setting.
