Gibbs film elasticity

https://doi.org/10.1351/goldbook.G02634
Pertains to a film element of a soap film changing in area at constant mass and is the differential change of its surface tension with relative change in area A, E=A (∂σ∂A)T,p,ni where T is the thermodynamic temperature, p is the pressure, and ni is the amount of substance of the species i.
