absorption
1. The take-up of a gas by a solid or liquid, or the take-up of a liquid by a solid. Absorption differs from adsorption in that the absorbed substance permeates the bulk of the absorbing substance.

2. The conversion of the energy of electromagnetic radiation, sound, streams of particles, etc., into ...
