    This is how gases tend to fill their containers. Indeed in the gas phase most of the volume is empty space only about 1/1 000th of the volume is actually taken up by matter (Figure 10.4 "Liquids and Gases"). It is this property of gases that explains why they can be compressed a fact that is considered in Chapter 6 "Gases".
