Wetness is the sensation caused by a liquid adhering to a solid surface.

Wetness is not a property of the liquid alone but a result of the interaction between the liquid and another surface. When water touches a solid, its molecules cling to that surface and spread out, forming a thin film. This film of liquid molecules stimulates sensory receptors in our skin, which our brain interprets as the feeling of being wet. So, wetness depends on both the liquid’s properties and the surface it contacts.
