Question

Derive the relationship between surface tension and surface energy

Answer 1

Surface Tension is defined as the force per unit length acting in the plane of interface between the plane or any other substance 

Surface Energy is defined as = 
 Work done to increase surface area
-----------------------------------------------
         Increase in surface area 
Relationship between them :-

$Surface Energy = \frac{Fd}{2(l*d)}$

$\frac{F}{2l} = Surface Tension$

$Surface Energy = Surface Tension$
