For a liquid-gas transition, L is the specific latent heat ( or specific enthalpy ) of vaporization; for a solid-gas transition, L is the specific latent heat of coexistence curve determines the rest of the curve.

In the above equations, \ mathbf u is the flow velocity vector, \ omega is the vorticity, v is the specific volume, p _ 0 is the stagnation pressure, T is temperature, s is specific entropy, h is specific enthalpy, \ mathbf { g } is specific body force, and n is the direction normal to the streamlines.

The specific enthalpy of fusion ( more commonly known as latent heat ) of water is 333.55 kJ / kg at 0 �C : the same amount of energy is required to melt ice as to warm ice from " 160 �C up to its melting point or to heat the same amount of water by about 80 �C . Of common substances, only that of ammonia is higher.
