2.2.1 Thermal expansion of solids, liquids and gases
1 Explain applications and consequences of thermal expansion in the context of common examples, including
the liquid-in-glass thermometer
2 Explain, in terms of the motion and arrangement of particles, the thermal expansion of solids, liquids and
gases, and state the relative order of magnitudes of the expansion of solids, liquids and gases
3 Convert temperatures between kelvin and degrees Celsius; recall and use the equation
T (in K) = θ (in °C) + 273
