Is there any relationship of latent heat with the regelation ?

Explanation

Yes there is relationship between latent heat and regelation .
(i) The amount of heat energy absorbed or relased during change of state in called Latent heat.
(ii) The phenomenon in which ice converts to liquids due to applied pressure and then reconverts to ice once the pressure is removed is called Regelation.
(iii) Since there are change of states during Regelation process latent heat is one of the factors affecing Regelation .
