Most of the liquid shrinks when it freezes. Water is a special exception because water expands when frozen quite large, one cubic meter of water would be 1.08 cubic meter of ice. Of course the ice would be less dense than water. This phenomenon has a beneficial effect. Imagine what happens if a pool of water such as rivers or lakes experiencing freezing temperatures.
If the surface water freezes, the ice would be less dense than water, and stay on the surface of the water does not freeze. Thus pool of water will freeze from top to bottom. Because the surface of the water acting as isolation against the water below, a total freeze was rare, except in the river or pond is very shallow.
If ice is more dense than water then the ice would sink to the bottom and let the water surface layer directly exposed to freezing temperatures. Finally, the entire pool of water would be frozen solid. Most of the water of life will be ruined. A long period of time disbursement required before the the river or lake is navigable again.
Sometimes the expansion that released by water when it freezes bring certain influences that are less pleasant. If the water in the pipe water supply system freezes, the expansion of ice will cause of the pipes broke.
This situation became known only after the occurrence of liquefaction. Then the water will flow again in the pipes, with a great leakage. Freezing of water in the cooling system can cause the car radiator pipes burst or even a breakdown of the engine block. That's why used an anti-freeze, which is a substance that has a lower freezing point than water.
