What is matter?

Matter is anything that has mass and volume (takes up space).

There are three physical states of matter. Solid, liquid and gas.

Solid ice Liquid water Iodine gas

Solids retain their shape. They have a fixed volume.

Liquids take up the shape of their container. They have a fixed volume.

Gases fill their container. They have a variable volume. This means the volume changes. It depends upon the volume of the container.
