How this relation formed
surface energy/area=surface tension?
In byju's video they derived that surface energy =Surface tension .
Please explain I am confused .

Surface energy per unit area =Surface tension
S.E/A=S.T
when A=1=>S.E=S.T
That's why both equations are shown
I will theoritically explain relation b/w surface energy and surface tension
Surface Energy
Surface energy and surface tension are two interconnected concepts. The molecules on the surface of a liquid are packed due to unbalanced intermolecular forces than the molecules at the center. This means there is a high energy density at the surface of a liquid.
Surface energy can be defined as the energy difference between the bulk of the material and the surface of the material. Surface energy is defined as the surface energy per unit surface area. The surface energy per unit area is identical to the surface tension measured. The units of surface energy are Jm
-2
. When the surface energy is provided by an external source, the liquid is said to be bubbling.
Surface Tension vs Surface Energy
- Surface tension has the units of Nm-1 and Jm-2 whereas surface energy has the unit Jm-2.
- Surface tension is measured along a line whereas surface energy is measured along an area.
