Short answer question: Adsorption: The phenomenon in which gas molecules, after colliding with a solid surface and losing some of their energy, become trapped on that surface and thus get concentrated and aggregated is known as adsorption. Adsorption is caused by the forces of interaction between the solid and the gas molecules. These forces are divided into physical forces and chemical forces, which respectively cause physical adsorption and chemical adsorption.
Correct. Adsorption: The phenomenon in which gas molecules, after colliding with a solid surface and losing some of their properties, become trapped on that surface and thus get concentrated and aggregated is known as adsorption. Adsorption is caused by the forces of interaction between the solid and the gas molecules. These forces are divided into physical forces and chemical forces, which respectively cause physical adsorption and chemical adsorption.

Adsorption refers to the attachment of atoms, ions, or molecules of a certain gas, liquid, or dissolved solid to a surface. This process results in the formation of a film composed of adsorbed substances on the surface. Adsorption is different from absorption; absorption refers to the process in which a liquid acting as an adsorbate penetrates into or dissolves in another liquid or solid. Adsorption is limited to the solid surface, whereas absorption acts on both the surface and the interior. Adsorption is also a type of mass transfer process; the molecules within a substance are attracted to the molecules surrounding them. However, the molecules on the surface of the substance experience forces that are not as strong as those acting from outside the substance. As a result, the surface of liquid or solid substances can adsorb other liquids or gases. This adsorption effect becomes particularly significant when the surface area is large. For this reason, industrial applications often make use of materials with large surface areas for adsorption purposes, such as activated carbon and water films.
