Students created a model of the water cycle by heating a beaker of water on a hot plate until it boiled. They carefully held a metal pan of ice cubes where water vapor was rising from the beaker and water drops began to form on the bottom of the metal pan. The water drops formed on the bottom of the pan because –

• A. the pan was made of metal

• B. the water vapor cooled

• C. the ice was a solid

• D. the hot plate uses electricity
