    Thermal expansion Wikipedia

    Thermal expansion is the tendency of matter to change its shape, area, and volume in response to a change in temperature.. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases. Thus, the molecules begin vibrating/moving more and usually maintain a greater average separation.
