Preferred Label : surface excess energy;
IUPAC definition : Defined by: \[U σ U - U α- U β U - V α\ \frac{U_{{m}} α}{V_{{m}} α} - V β\ \frac{U_{{m}}
β}{V_{{m}} β}\] where V α and V β satisfy the condition V α V β V, the total volume
of the system. (U m α V m α) and (U m β V m β) are the energy densities in the two
bulk phases where U m α and U m β are the mean molar energies and V m α and V m β
are the mean molar volumes of the two phases.;
