Surface tension

The surface tension $\gamma$ is a measure of the work required to build up a surface ....

Canonical Ensemble: Two phases;

$\gamma ={\frac {\partial F(N,V,T,A)}{\partial A}}$;

where

• $N$ is the number of particles

... preliminary version (sketchy) to be continued soon, as soon as I find a way to distinghuis A (Helmholtz) and A (surface area)
