Answer: (b) Contact between silica gel and vapour of water. Adsorption is a surface-area-dependent phenomenon in which molecules are held on the surface of a material by weak attractive forces. It is typically associated with molecules, such as water vapor, that can easily be adsorbed onto a variety of surfaces. Silica gel is a common material used in adsorption due to its porous structure, allowing it to adsorb large amounts of water vapor and other molecules.
