Question

Define the term surface energy write down its formula and units

Answer 1

Surface free energy or interfacial free energy or surface energy quantifies the disruption of intermolecular bonds that occurs when a surface is created.

Surface energy has the dimension of force per unit length (dyne/cm – cgs units) or of energy per unit area (mN/m – SI units).

The general formula for measuring surface tension is: gamma equals force divided by length.

Surface tension formula

Gamma represents surface tension, F represents force, and d represents the length along which the force is felt.
