Stefan's formula about specific surface energy

Stefan’s formula says that the specific surface energy at a given interface is determined by the respective enthalpy difference $\scriptstyle \Delta H^*$ .

$\sigma = \gamma_0 \left( \frac{\Delta H^*}{N_A^{1/3}V_m^{2/3}}\right),$

where σ is the specific surface energy, N_A is Avogadro's number, γ₀ is a steric dimensionless coefficient, and V_m is the molar volume.
