Physics:Stefan's formula

In thermodynamics, Stefan's formula says that the specific surface energy at a given interface is determined by the respective enthalpy difference [math]\displaystyle{ \Delta H^* }[/math]. [math]\displaystyle{ \sigma = \gamma_0 \left( \frac{\Delta H^*}{N_\text{A}^{1/3}V_\text{m}^{2/3}}\right), }[/math] where σ is the specific surface energy, N_A is the Avogadro constant, [math]\displaystyle{ \gamma_0 }[/math] is a steric dimensionless coefficient, and V_m is the molar volume.Template:BSN
