Phase change when heat is removed from a liquid?

Explanation:
When heat is removed from a liquid, the molecules lose kinetic energy and move more slowly. As the temperature drops to the freezing point, the molecular motion becomes insufficient to keep the liquid in its fluid state, and the particles lock into an orderly structure to form a solid. This change is freezing, the process of liquid turning into solid due to cooling. It’s the opposite of melting, which requires adding heat to overcome the forces that hold a solid together. Evaporation and sublimation involve gaining energy to break intermolecular bonds and transition to gas, not cooling.
