absorption
Let an agent explain absorption as a bulk uptake process across physics, chemistry and physiology, distinguish it from adsorption, describe measurement and models, and support engineering, biological and learning questions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain absorption as a bulk uptake process across physics, chemistry and physiology, distinguish it from adsorption, describe measurement and models, and support engineering, biological and learning questions.
A physical or chemical process in which atoms, molecules, ions or energy are taken up into the bulk of another material or system, as when a gas dissolves into a liquid, a liquid is taken into a porous solid, light is absorbed by matter, or nutrients and drugs are absorbed physiologically through membranes, and including reabsorption in the kidney; absorption is distinguished from adsorption, which occurs on surfaces, and is described by absorption isotherms and coefficients.
What it is for: Uptake into the bulk of a material.
It can be explain the process; distinguish from adsorption; describe measurement; support cross-field questions.

What it looks like
Not physical; a process.
How it is recognised
Uptake into bulk
Gas, liquid, light, physiological
Adsorption is surface binding; diffusion is spreading; sorption covers both
