Latent Heat of Fusion | Latent Heat of Evaporation

If you add heat to some substance it will not necessarily change temperature.

Energy also can work towards producing a phase change, such as from solid to liquid or liquid to gas.

Water might heat up and change temperature or some portion of it might turn instantly to steam, leaving the rest of the water at the same temperature.

The “latent heat of fusion” and “latent heat of evaporation” will vary for different materials and can be used to calculate the energy necessary for these changes.
