Since ice floats in water, then ice is lighter than water Another way to view this is that if you freeze a bottle of water, the bottle will expand when the water has turned to ice. This demonstrates that when water is converted to ice, it takes up more space (volume), thus has less mass for the same volume

Water is unusual in that its maximum density occurs as a liquid, rather than as a solid. This means ice floats on water. Density is the mass per unit volume of a material. For all substances, density changes with temperature.The mass of material does not change, but the volume or space that it occupies either increases or decreases with temperature.

"Heavy ice" is 10.6 percent denser than normal water because the ice is made from "heavy water". Heavy water, D 2 O instead of H 2 O, is water in which both hydrogen atoms have been replaced with deuterium, the isotope of hydrogen containing one proton and one neutron. Heavy water is indeed heavier than normal water (which contains a tiny ...

The additional space created reduces the density of the water as it freezes, making ice less dense than water. Rather than the molecules packing more tightly together and creating a heavier density, as water freezes the hydrogen bonds increase from a 3.4-molecule bond to a 4-molecule bond, which creates the excess space and reduced density in ice.

Well what would happen is the water up here would freeze. And this is actually what does happen. Water at the surface would freeze, but if this ice were more dense, the solid water were more dense than the liquid water, well then the ice would sink. The ice would sink and collect at the bottom. The ice would collect at the bottom right over here.

Best Answer: Water is heavier than the same volume of ice. If you take a litre of water, which weighs 1kg., and freeze it, then the resulting block of ice will also weigh 1kg. It still has the same number of molecules in it -- they are just sticking together as a solid, as opposed to flowing freely past one another as a liquid.

From there getting warmer it because less dense and when it is lower than 4 C, water stays around the same density because of its ice state. If ice was heavier than water and didn't float it would ...

In general, if ice and water have the same volume, then the ice weighs less. This is because ice is less dense than water and occupies more space. Therefore, a gallon of ice weighs less than a gallon of water. When water freezes into ice, the individual water molecules expand to occupy more space, increasing in volume by about 9 percent.

Ice is strange, in that the solid form is less dense than the liquid water it freezes from. This causes Ice to float on top of the water. How would our planet earth be different if something changed this property of Ice so that it became significantly denser than water.

Chris - Hot water is actually a little bit heavier than cold water because, as Einstein told us, E=mc2. So if E, the energy in the water, goes up because it's hotter, then mass, m, must also go up to keep the equation balanced [c, the speed of light in a vaccuum, doesn't change].
