### Thermal Expansion of Solids and Liquids Physics

Thermal expansion is large for gases and relatively small but not negligible for liquids and solids. Linear thermal expansion is ΔL = αLΔT where ΔL is the change in length L ΔT is the change in temperature and α is the coefficient of linear expansion which varies slightly with temperature.
