During a phase change at constant pressure, the temperature remains constant while heat energy is absorbed (for melting/boiling/sublimation) or released (for freezing/condensation/deposition). This energy is used to change the state (break or form intermolecular bonds) rather than increase the kinetic energy of the molecules, which would result in a temperature change.
Latent heat corresponds to the change in heat at constant
