Witryna2 mar 2024 · Expert's answer. When ice melts to liquid water, it is an endothermic process because heat must be absorbed to melt the ice without a change in temperature (Latent heat of fusion). When liquid water freezes to ice, the process is exothermic because energy is given out for the liquid water to form a more stable ice. georgios indianapolis downtownWitryna2.
