Preferred Label : Gibbs film elasticity;
IUPAC definition : 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, \[E
A\ (\frac{ σ }{ A})_{T,p,n_{i}}\] where T is the thermodynamic temperature, p is
the pressure, and n i is the amount of substance of the species i.;
