Explain why the temperature of the ice does not change. What does change? The heat is released by the ice, providing the energy required to partially overcome intermolecular attractive forces in the solid and causing a phase transition to liquid water. The solution remains at 0 °C until all the ice is melted. The heat is absorbed by the ice, providing the energy required to partially overcome intermolecular attractive forces in the solid and causing a phase transition to gaseous water. The solution remains at 0 °C until all the ice is melted.
