SURFACE TENSION: Surface Tension on Liquid Droplet, Surface Tension on a Hallow Bubble, Surface Tension on a Liquid Jet

Surface tension is defined as the tensile force acting on the surface of a liquid is contact with a gas or on the surface behaves like a membrane under tension. The magnitude of this force per unit length of free surface will have the same value as the surface energy per unit area. It is denoted by 𝜍 (sigma). In MKS units it is expressed as Kg f/m while in SI units as N/m
