Surface tension: Difference between revisions

Latest revision as of 15:16, 20 February 2012

surface tension

(Also called surface energy, surface free energy, capillary forces, interfacial tension.) The tangential force acting at the interface between a liquid and air (or, more correctly, its own vapor) caused by the difference in attraction between liquid molecules and gaseous molecules.

Expressed either as a force per unit length of interface or as an energy per unit area of interface.
