An ice cube tray full of water is put into a freezer .which energy change occurs in the particles in the water as it undergose a phase change from a liquid to solid

Answer 1

When the water in the ice cube tray undergoes a phase change from liquid to solid (freezing), the particles in the water experience a decrease in kinetic energy. This occurs because, as the temperature drops, the water molecules move more slowly and lose energy.

During the freezing process, the water molecules begin to form a structured arrangement (a crystalline structure) as they transition into ice. This process releases energy in the form of heat to the surrounding environment—this energy is known as the latent heat of fusion.

In summary, as the water freezes, the particles lose kinetic energy, and energy is released to the surroundings, allowing the formation of solid ice.
