The molecules of the water loosen when cooled
WebCooling a liquid decreases the speed of the molecules. A decrease in the speed of the molecules allows the attractions between molecules to bring them a little closer together. Summary Students add food coloring to hot … WebDec 8, 2016 · As the molecules of a liquid are cooled they slow down. As the molecules slow down they take up less volume. Taking up less room because of the molecules lower energy causes the liquid to contract. An exception to this is water. As water cools it contracts until it reaches the freezing point.
