• ### Thermal expansionWikipedia

Thermal expansion is the tendency of matter to change its shape area volume and density in response to a change in temperature usually not including phase transitions.. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated molecules begin to vibrate and move more usually creating more distance between themselves.
