ability of a liquid to spread on a solid surface

Wettability refers to the ability of a liquid to maintain contact with a solid surface, influenced by the intermolecular interactions between the liquid and the solid. For example, if you spill water on a surface and it spreads out, the surface has high wettability; if the water beads up, the surface has low wettability. This concept is crucial in fields like material science and biology, where it affects processes such as coating, adhesion, and even the behavior of biological tissues.
