Matter can be found in different forms. Some things are solid like a rock or a toy. Solids have fix mass, shape and volume. Other things are liquid like water or juice. Liquids have fix mass and volume. But they do not have fix shape. They take the shape of their container. Then there are things like air which we can't see, but it's still there! We call that gas. Gases also have fix mass with no fix shape and volume.
