All pure substances do.
Many substances with mixed compositions do also, although not all (for instance, you'll never see cotton as a liquid... or liquid wood...).
Water. That is why ice floats on the top of a lake.
im going to say water and ice
This is water (H2O).
Yes true, however this is not true of H2O or water. Water in solid form is actually less dense than its liquid form. That is why ice floats on water.
No. Exactly the opposite. Water is the only known substance whose solid form floats in its liquid form. Which, incidentally, is a lucky accident, since life on earth would be impossible if ice sank in water.
Ice is water in its solid form. When it melts, it is water in its liquid form.
When liquid becomes a solid it has to loose temperature. Because when a substance transforms into solid from liquid the atoms of that substance has to come closer to form the solid form.
Water! As a liquid, water has a density of approximatly 1 g/mL. Ice, however, has a density of about 0.92 g/mL. This is, in fact, the reason that ice floats in water.
The water in ice has a larger volume that water in its liquid form. That is why Ice floats. Ice is less dense than liquid water.
Besides water, a substance in solid form is more dense. At the least dense substance floats, HN03 will not float in liquid HN03. ;)

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.
Water in its solid form is a crystalline structure. It is one of the few substances that is less dense in solid form than in liquid form. So, being less dense, it floats.
No. Exactly the opposite. Water is the only known substance whose solid form floats in its liquid form. Which, incidentally, is a lucky accident, since life on earth would be impossible if ice sank in water.
ice cubes floats in the water, because it is in the liquid form
Ice is water in its solid form. When it melts, it is water in its liquid form.
A solid and a liquid can form a solution, a suspension, the can chemically react, etc.
When liquid becomes a solid it has to loose temperature. Because when a substance transforms into solid from liquid the atoms of that substance has to come closer to form the solid form.
If the solid is less dense than the liquid, it floats on top. If it is of relatively equal density as the liquid it forms a colloid in which the solid and the liquid solvent are still distinct and separate, but fairly equally distributed . If it is more dense than the liquid, it precipitates out, to the bottom of the liquid. ChaosRu
Water has many unique properties that enabled life to evolve on Earth. The one that is unique is that it expands when it freezes, thus lowering its density. This means that ice floats on water. It is the only compound or element where the solid form floats on the liquid form.
