... A molecule of water (chemical formula, H2O) contains two atoms of hydrogen and one atom of oxygen. Because it is much heavier than hydrogen, oxygen provides about 89 percent of the weight of a water molecule. Whether water is in a liquid state, a solid state (ice), or a gaseous state (water vapor or steam), its chemical makeup remains the same. The three physical states of water depend upon the motion of water molecules, which in turn depends upon heat. In ice, for example, the water molecules have lost so much heat that they move slowly. Electrical attraction between the molecules then becomes strong enough to bind them together in a fixed arrangement with little molecular motion; thus ice holds its shape....

A water molecule consists of one atom of oxygen and two atoms of hydrogen. Fresh water freezes at 32 degrees Fahrenheit, although the freezing point of salt water is lower. Bibliography:
