The latent heat of fusion is constant; other latent heats decrease as temperature increases.

The equation for the latent heat of vaporization of water is:

${L}_{v}$ = (25.00 – 0.022 74 T) × 10⁵ J/kg

For the latent heat of fusion,

${L}_{f}$ = 3.34 × 10⁵ J/kg

For the latent heat of sublimation,

${L}_{s}$ = (28.34 – 0.001 49 T) × 10⁵ J/kg

In each of the above expressions, the temperature $T$ is in Celsius degrees.
