refers to the action of both absorption
taking place simultaneously. As such it is the effect of gases or liquids being incorporated into a material of a different state and
adhering to the surface of another molecule. Absorption is the incorporation of a substance in one state into another of a different state (e.g., liquids being absorbed by a solid or gases being absorbed by a liquid). Adsorption is the physical adherence or bonding of ions and molecules onto the surface of another molecule.
