Water is a chemical substance. A single water molecule contains two hydrogen atoms and one oxygen atom bonded together. The chemical formula for water is H2O. Water can be in one of three states. Water can be in a liquid sate, gas state (vapor) or solid state. An example of water in a liquid state is water in a lake. An example of water in a solid state is ice. An example of water in a gas state (vapor) is the steam coming off a boiling pot of water.
