Water can be a solid , a liquid or a gas, depending on the temperature it has. At 32° F (0° C) water freezes and turns into ice. It expands and becomes lighter. As a result ice floats on water. That is why you should let water out of pipes during the wintertime because it may freeze and burst the pipes. At 212°F (100°C) water boils and escapes as a vapor into the air. Between these two states water is a liquid. Most of the world’s water is in liquid form. It can be found everywhere on earth.
