Wetting is a term used to describe the process in which a liquid spreads over and adheres to the surface of a solid material. It refers to the interaction between a liquid and a solid, resulting in the formation of a thin film of the liquid on the solid surface. This phenomenon is governed by intermolecular forces, specifically between the liquid molecules and the molecules on the solid surface.
When a liquid wets a solid, it means that the surface tension of the liquid is lower than the surface energy of the solid, allowing the liquid to spread and maintain contact with the solid material. Wetting can be influenced by various factors, including the type of liquid, characteristics of the solid surface such as roughness or porosity, temperature, and the presence of chemical additives.
The degree of wetting is typically measured by contact angle, which is the angle formed between the solid surface and the tangent line at the contact point of the liquid drop. A lower contact angle indicates a higher degree of wetting, implying that the liquid spreads more easily on the solid surface. Conversely, a higher contact angle suggests lower wetting ability, resulting in the formation of droplets or a lack of liquid adhesion.
Wetting phenomena have significant implications in various fields, such as materials science, chemistry, physics, and engineering, as they influence processes like coating, adhesion, surface treatments, and fluid flow dynamics. Understanding wetting behavior is crucial for designing and optimizing processes involving liquid-solid interactions.

The word "wetting" is derived from the verb "wet", which dates back to Old English and Middle English. It originally comes from the Proto-Germanic word "wetjaną", meaning "to wet, moisten". This word can be traced back to the Proto-Indo-European root "wed-", which meant "water, wet". The word "wetting" emerged as a noun form of "wet" in the 17th century and refers to the act of making something wet or moist.
