Water is very important to living things. Without water there can be no life on the earth. All animals and plants need water. Man also needs water.
The water in seas, rivers and lakes is a liquid. But in the air it is not a liquid but a gas, and it is all around us. Snow and ice are made of water, too. They are frozen water. This kind of water is a solid.
Water may be a solid, or a liquid, or a gas. When it is a solid, it may be as hard as stone. When it is a liquid, you can wash something in it. When it is a gas, you can"t see or feel it. Water has three states.
[A] True
[B] False
