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.

Enthalpy of fusion or melting. This applies to the transition of a solid to a liquid and is designated ΔH m. Enthalpy of vaporization. This applies to the transition of a liquid to a vapor and is designated ΔH v. Enthalpy of sublimation. This applies to the transition of a solid to a vapor and is designated ΔH s.

where ΔH fus is the heat of fusion which is always positive, and ΔV fus is the volume change for fusion. For most substances ΔV fus is positive so that the slope is positive. However for water and other exceptions, ΔV fus is negative so that the slope is negative.
