Question

What is surface energy? Establish the relation between surface tension and surface energy.

Answer 1

Surface energy is defined as the amount of the work done against the force of surface tension, in forming the liquid surface of a given area at a constant temperature.

Answer 2

Dear Natasha,

◆ Surface energy -

- Surface energy is the work required to increase unit area in creating new surface at constant temperature, pressure and composition.

# Relationship between surface tension & surface energy -

Let T be surface tension & E be surface energy for a liquid with surface area A.

They are related as -

E = A × T

Hope this helps you. Thanks for asking...
