Absorption (chemistry) - Wikipedia A more common definition is that "Absorption is a chemical or physical phenomenon in which the molecules, atoms and ions of the substance getting absorbed enter into the bulk phase (gas, liquid or solid) of the material in which it is taken up "
Absorption | Definition, Coefficient, Facts | Britannica All known transparent substances show absorption to some extent For instance, the ocean appears to be transparent to sunlight near the surface, but it becomes opaque with depth Substances are selectively absorbing; that is, they absorb radiation of specific wavelengths

Absorption: Understanding the Science Behind Its Process Absorption involves the incorporation of molecules into a bulk substance, while adsorption denotes the adhesion of molecules to a surface without penetrating it The primary distinction lies in the depth of interaction: absorption is a volumetric phenomenon, whereas adsorption is superficial
