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...).
Not always - the density of a liquid may be greater or less than that of the solid form depending on the molecular structure and arrangement. For example, water is an exception as its solid form (ice) is less dense than its liquid form.
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.
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.
Frozen water, ice, is less dense than the water from which it is formed. Which is a GOOD idea, otherwise if it were heavier, it would sink, and the fish would get stuck! (As my old teacher put it.)
Water can be solid, liquid or a gas.A solid in the form of ice.A liquid in the form of water.A gas in the form of vapour.
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. ;)

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.
ice cubes floats in the water, because it is in the liquid form

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.
A solid and a liquid can form a solution, a suspension, the can chemically react, etc.
No. It is a liquid.
solid with hydrogen bonds making it less dense than its liquid form
Frozen water, ice, is less dense than the water from which it is formed. Which is a GOOD idea, otherwise if it were heavier, it would sink, and the fish would get stuck! (As my old teacher put it.)
