States of Matter

Matter comes in many forms. At this point, we will consider three: solid, liquid and gas. A solid has a definite shape and it takes up a fixed volume. On the other hand, liquid has a fixed volume, but no definite shape. A liquid will change its shape to fit its container. A gas has no definite shape and no fixed volume. Like a liquid, a gas will change its shape to fit its container, but it will also expand to fill the entire volume of the container.

Solid (s) rigid, fixed volume, fixed shape.
Liquid (l) definite volume, but no definite shape.
Gas (g) no fixed shape, no fixed volume.
