SURFACE TENSION

Surface tension is the tension produce in surface of liquid pour in a tube and any porous medium. The molecules of water present in bulk exerts a force in all directions but the force is zero inside the bulk of the liquid due to force exert by neighbouring molecule and net force is zero in the bulk of liquid. At the surface the molecule is feel downward force due to the particle in bulk and the surface is squees as much as possible.
