Wetting refers to the ability of a liquid to maintain contact with a solid surface, which is influenced by intermolecular forces. This property is crucial in determining how liquids spread over or penetrate into solids, and it is greatly affected by the presence of surfactants, which can modify surface tension. The extent of wetting is quantified by the contact angle, which plays a significant role in capillary action within colloidal systems.
