question: Sean is trying to see how fast the water molecules are moving in a container of water. He observes that the molecules are moving very slowly, so the temperature must be
choices.text: cool warm
choices.label: A B
para: When a volume of water is cooled, the molecules move less vigorously, so same number of molecules takes up less space and the water is denser.
