WATER TURNS TO ICE Water is perhaps the most abundant liquid known to man. It is needed to sustain the lives of all living things and covers nearly three quarters of the earths surface. It is a molecule made up of two hydrogen atoms and one oxygen atom (H O). Both hydrogens are bonded to the one oxygen atom covalently. At room temperature it is a liquid. At temperatures of over 100°C it is a …showed first 75 words of 526 total…

Because the H-bonds have formed between each molecule, the molecules are actually further away from each other than they were in the liquid form (a rare property of any substance). This means that the solid form of water is actually less dense than the liquid. This solid state of water will float on the liquid form. It is known as ice.
