Answer:
Thermal expansion of solids, liquids and gases. All three states of matter (solid, liquid and gas) expand when heated. The atoms themselves do not expand, but the volume they take up does. However, gases that are contained in a fixed volume cannot expand - and so increases in temperature result in increases in pressure .
