Is melting an endothermic or exothermic
In thermochemistry, an endothermic process (from Greek ἔνδον (endon) 'within', and θερμ- (therm) 'hot, warm') is any thermodynamic process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system. Thus, an endothermic reaction generally leads to an increase in the temperature of the system and a decrease in that of the surroundings. It ma… WitrynaMelting is endothermic. Melting process needs energy to convert it from solid to liquid state. Ice melts when heat energy causes the molecules to move faster, breaking of hydrogen bonds between molecules to form liquid water.
