Pure water is tasteless, odourless, and colourless. Water can occur in three states: solid (ice), liquid, or gas (vapour).

Solid water—ice is frozen form of water. When water freezes, its molecules move farther apart, making ice less dense than water. This means that ice will be lighter than the same volume of water, and so ice will float in water.

Liquid water is the form of water with which we are most familiar. We use liquid water in many ways, including washing and drinking.

Water as a gas — vapour is always present in the air around us. We cannot see it. When we boil water, the water changes from a liquid to gas or water vapour. As some of the water vapour cools, we see it as a small cloud called steam.
