In 3 to 5 sentences, describe how the kinetic energy of molecules and the forces of attraction between molecules change as ice melts into water.

Answer 1

As ice melts into water, the kinetic energy of molecules increases. The molecules are no longer confined in a rigid lattice structure, so they gain more freedom of movement and increase their kinetic energy. At the same time, the forces of attraction between molecules weaken. In the solid state of ice, the molecules are tightly packed and held together by strong intermolecular forces. However, as ice melts, these forces weaken, allowing the molecules to move more freely and spread apart.
