Explain Surface Tension and surface energy.

Explanation

Surface tension the force per unit length on a imaginary line drawn on the surface of the liquid and acting perpendicular to it.
Dimensional formula: `(Force)/(Leng th)=(MLT^-2)/L`
`= MT^-2`, Unit : `n ewt on // metre`
Surface energy: The work done to increase the surface area of a liquid is called surface energy.
Surface energy= Surface tension `times` Increase in surface area.
