What happens at the molecular level when water Melts freezes and boils?

Answer 1

When water freezes, the molecules slow down and form a structured lattice arrangement, resulting in solid ice. During melting, heat energy is absorbed, causing the molecules to gain kinetic energy and break free from their rigid structure, transitioning into a liquid state. When water boils, additional heat energy increases the kinetic energy further, allowing the molecules to escape the liquid phase and enter the gas phase as water vapor. Throughout these processes, hydrogen bonds between water molecules play a crucial role in stabilizing the different states.
