Surface Energy Density and Surface Tension
Thus it is clear that the surface of the
liquid must have a higher energy than
Sometimes the unit is given equivalently Thus γ = f / L as Nm-1, particularly when quoted as a surface tension. The surface energy density is: (f dx) / (L dx) = f/L = γ , i.e.

We can use a virtual work argument to show this for a force f acting on an area dA and moving through a distance dx: L f
