Since water is present in many foods, evaporation that occurs as food is cooked or heated causes the food to dry out. When salt is dissolved into water, the salt is said to have entered the aqueous state. We use dry ice, which is solid CO2, as a refrigerant (solid to gas), and we make artificial snow for skiing and snowboarding by transforming a liquid to a solid. Children will learn: What is meant by the terms reversible and irreversible change, and be able to provide examples of both.
