Expansion, Gas Laws, Thermometers, Kinetic Theory and Molecular Size,Gases, solids and liquids usually expand when heated. For a given temperature rise, gases expand more than liquids and liquids expand more than solids. Water has the unusual property of contracting as it is heated from 0°C to 4°C; it has its maximum density at 4°C (see Example 6.12).
