WebJun 22, 2010 · As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different. When liquid water freezes into solid ice, it becomes less dense. When ice forms, water molecules arrange themselves into a rigid but open pattern. WebNov 28, 2007 · Well, yes, but the density change of water within dive-able temperatures is negligible. For example, taking two extremes: water at 33.8°F is only 0.43% more dense than water at 86°F. So if you make 50 pounds of buoyancy in the tropics, you'll make 50.2 pounds in the arctic. Similarly, water isn't really incompressible as dive text claim.
