Water changes its state through heating and cooling. When heated, it turns into steam (gas), and when cooled, it becomes ice (solid). These changes occur due to variations in temperature and energy.

Water changes its state by either gaining or losing energy. When heated, water molecules move faster and spread out, turning into steam (gas). Conversely, when cooled, the molecules slow down and arrange into a solid structure, forming ice. This process of changing from liquid to gas is called evaporation, and from liquid to solid is called freezing. These state changes are reversible, meaning that steam can condense back into water, and ice can melt back into liquid form when the temperature changes.
