Surface tension is the elastic force acting on the surface of a liquid, caused by the attraction of molecules in the surface layer. This property makes the liquid’s surface act as if it were covered by a thinx, elastic film.
Surface tension plays a role in phenomena such as the formation of droplets, capillarity, and the ability of certain insects to walk on water.
It is measured in units of energy per unit area and is influenced by the cohesion between the liquid’s molecules.
