Stefan number
The Stefan number (St or Ste) is defined as the ratio of sensible heat to latent heat. It is given by the formula S t e = c p Δ T L , {\displaystyle \mathrm {Ste} ={\frac {c_{p}\Delta T}{L}},} where cp is the specific heat, cp is the specific heat of solid phase in the freezing process while cp is the specific heat of liquid phase in the melting process.
