Thermal expansion
Thermal expansion is a change in a material’s dimensions as its temperature changes. A simple coefficient model approximates the change over a limited temperature range and depends on the material and geometry. For example, leaving gaps between sections of a metal rail allows space for expansion in warmer conditions.
