Answer:
D. Water changes state when it loses or gains energy.
Explanation:
When water gains energy, it turns from ice to water, or water to gas. When water loses energy, it turns from gas to water, or water to ice.
Particles in the water move faster and create more energy when heated, and this causes them to spread wider apart and change. Particles slow down and move closer together when they get cold.
