WebA) Warm water has lower density than cold water. B) Water decreases its volume when it freezes. C) Water molecules move apart slightly as temperatures cool below 4oC. D) Water vapor is less dense than dry air alone. A) Density decreases as salt is added. WebJan 21, 2015 · Kuba Dolecki. Jan 21, 2015. Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions. Because the molecules are not moving, they're not able to form as many hydrogen bonds with other water molecules.
