Define Surface Tension

Surface tension is defined as the tensile force acting on the surface of the liquid in contact with a gas or on the surface between two immiscible liquids such that the contact surface behaves like a membrane under tension.


Surface Tension, σ = Force/Length                        (N/m)


σwater = 0.0725 N/m                σMercury = 0.52 N/m
