SOLIDS, LIQUIDS AND GASES

Everything is made of matter. Matter can be in three states:

-          Solids: fixed shape and same size. For example, iron, aluminium and glass.

-          Liquids: they adapt to the container but do not expand. They flow. For example, wáter, milk, etc.

-          Gases: they expand and they are invisible. For example, natural gas and butane.
