By the end you’ll be able to

describe and explain thermal expansion in solids, liquids and gases in terms of increased particle motion and spacing
apply the idea that, for a fixed mass of gas, pressure and volume are related when temperature is constant
apply the idea that, for a fixed mass of gas at constant pressure, volume increases as temperature increases
