When does a material typically undergo latent heat of solidification?

A material undergoes latent heat of solidification when it reaches its freezing point and begins to change from a liquid to a solid state. At this stage, the temperature of the material remains constant even as heat is removed. The energy released during this phase change is referred to as latent heat, which is necessary to break the intermolecular bonds that hold the liquid together.

During solidification, the substance does not actually cool down further until all of it has transitioned into solid form; hence the process is tied to reaching the freezing point. Other options do not accurately represent the conditions under which latent heat of solidification occurs. For instance, heating to boiling point involves phase change from liquid to gas rather than solidification, while rapid cooling may not allow for a stable solid phase to form, and mixing with another substance could result in various thermal effects, but is not directly related to the solidification of a single material.
