WebSo, surface tension is due to cohesion between the water molecules at the surface of a liquid, but water molecules aren't just attracted to each other. They're actually attracted to the container too and other materials, and that's called adhesion. WebJan 1, 2011 · Surface tension is defined as the work required to increase the area of a surface isothermally and reversibly by unit amount.Surface tension (γ) is expressed as surface energy per unit area and alternatively as force per unit length.Surface tension of liquids can be measured directly and expressed in the units of work or energy per unit …
