Question

What is physical absorption..??.. ​

Answer 1

Physical absorption — A non-reactive process e.g. when oxygen present in air dissolves in water. The process depends on the liquid and the gas, and on physical properties like solubility, temperature and pressure. Chemical absorption — A chemical reaction takes place when the atoms or molecules are absorbed.

OR

Physisorption, also called physical adsorption, is a process in which the electronic structure of the atom or molecule is barely perturbed upon adsorption.

OR

Physical adsorption, or physisorption, is a type of adsorption that occurs for most particles in contact with a solid or liquid surface. Condensation of water molecules sticking to a drinking glass is an example. ... In other words, the molecules desorb from the surface.
