Surface Tension

Subject: Chemistry

Book: General Chemistry

Surface tension is the energy required to increase the surface area of a liquid. It arises from cohesive forces among liquid molecules and is measured in N/m (SI unit). Water’s high surface tension allows insects to walk on its surface and is reduced by surfactants like detergents. Control of surface tension is important in coatings, emulsions, and cleaning processes.
