Stefan's formula

= 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 $scriptstyle\; Delta\; H^*$.

: $sigma\; =\; gamma\_0\; left(\; frac\{Delta\; H^*\}\{N\_A^\{1/3\}V\_m^\{2/3\; ight),$

where σ is the specific surface energy, "N"_"A" is Avogadro's number, $gamma\_0$ is a steric dimensionless coefficient, and "V"_"m" is the molar volume.

Yet another Stefan's formula

Stefan's formula (not to be confused with the Stefan's law) describes the dependence of the thickness of ice cover on freezing temperature.
