Technically it's neither true nor false without additional information (we would need to know the temperature and pressure). However, for "ordinary" conditions that you might find on or near the surface of the Earth, ice (solid water) is less dense than water (liquid water).
Ice is less dense than water.
solid with hydrogen bonds making it less dense than its liquid form
The fact that water's solid phase is less dense than its liquid phase is important for aquatic organisms because it means that they will be able to live below the ice. This is evident when a lake freezes over to a certain extent while the fish and aquatic life is fine until the ice melts.
The liquid to gas phase change is vaporizing; the reverse is condensing. The other phase changes are: - solid to liquid: melting - liquid to solid: freezing - solid to gas: sublimation - gas to solid: deposition
No, solid O2 will not float on liquid O2 at all. There are several different phases of solid oxygen, depending on the conditions under which it is formed. But all of them are more dense than the liquid form, even near its freezing point (where it is most dense). None will come close to floating. Liquid oxygen has a density of about 1.141 grams/ml or so, and the solid forms have densities in the area of 1.4 grams/ml or so. Very few substances have a solid phase that floats on its liquid phase. Water is almost miraculous in this physical phenomenon. If ice did not float on water, earth's oceans would freeze solid within a few thousand years (or less).
Solid to liquid.
Solid Argon is more dense than the liquid phase
The gas phase is less dense than the liquid or solid phase of a substance. Density is not a property of sound.
False. Solidification when a substance that is in a liquid changes phase to a solid.
This question is based on a false assumption that the outer core is solid and the inner core is liquid. This is incorrect. It is in fact the inner core that is solid (and so is the most dense) and the outer core which is liquid.
Ice floats. Most other substances are denser in the solid state.
The best example is ice, which is the solid form of the liquid we call water. Water's solid form (ice) floats on its liquid form, as we know.
This depends on how dense the solid is, and how dense the liquid is.
The melting phase changes are Solid~Liquid~Gas and the freezing phase changes are Gas~Liquid~Solid
Liquid to solid is a phase change.
