Question

what is surface energy? show that the durface tension of a liquid is equal to its surface energy per unit area​

Answer 1

Answer:

$\huge{Answer}$

• The work done to increase the surface area of a liquid film by unity is equal to the surface tension. So the surface energy per unit area is equal to the surface tension.

• Surface tension is the net intermolecular force on the surface molecules of a liquid. Surface energy is the relevant energy of these bonds.
