ABsorption is chemistry, physics vocabulary. ADsorbtion too. So what’s the difference between absorption and adsorption? Is there a difference between absorption and adsorption? Quick Explanation: Absorption is when one substance enters completely into another. Think of people walking into and sitting down in a car trolley. Adsorption is when one substance just hangs onto the outside of another. Think of people holding onto a car trolley with one hand and leaning off the side. They’re along for the ride but not inside.
