Question

Derivation of surface energy​

Answer 1

Answer:

Since the value of force is given as F=2Tl. This work is stored as potential energy in the unit surface. The surface energy is this potential energy. The above relation shows that the surface energy is equal to its surface tension per unit area of a liquid.
