Hiii mate.
Latent heat is taken in / or given out when a material changes state e.g. solid to liquid or liquid to gas.
Regelation is the phenomenon of melting under pressure and freezing again when the pressure is reduced. Many sources[who?] state that regelation can be demonstrated by looping a fine wire around a block of ice, with a heavy weight attached to it. The pressure exerted on the ice slowly melts it locally, permitting the wire to pass through the entire block. The wire's track will refill as soon as pressure is relieved, so the ice block will remain solid even after wire passes completely through. This experiment is possible for ice at −10 °C or cooler, and while essentially valid.

Latent heat is the amount of heat released during a change of state, i.e. the boiling of water or the melting of ice.
Specific heat is the amount of heat required to raise the temperature of a substance a certain amount.
