Is making ice cubes exothermic
Witryna22 cze 2024 · Basically, melting ice is an endothermic reaction because the ice … WitrynaThis works because ice thawing is endothermic; energy (heat) is used up to turn solid into liquid even though the temperature is staying the same. The freezing point of water is 0 ∘ C, so water-ice slush stays at 0 ∘ C. If it was lower, it would stabilize at the lower temperature. By adding salt, you are lowering the freezing temperature.
