Question

define surface tension derive a relation between surface tension and surface energy what is the unit of surface tension

Answer 1

Explanation:

Surface energy is defined as the work done per unit area to increase the free surface area, under isothermal condition. ∴Surfacee≠r≥y=Work doneFree surface area=WdA=T(2Ldx)2Ldx=T. ∴ Surface energy is equal to surface tension.

Answer 2

Hey brainly user

Here is your answer

Surface tension is defined as the force acting per unit length perpendicular to the line drawn on the surface of the liquid

Unit : NM^-1 or KgS-2
