Chemically, water(H2O) is two molecules of Hydrogen, and one molecule of Oxygen. Water by definition is usually a liquid, although it can be converted to different states by the removal or addition of heat. Water heated to 100 degrees Celcius begins to convert to steam, a gaseous state, and when cooled to 0 degrees Celcius converts to ice, a solid state.
