Dl expansion in dt temperature differences c or k h heat transfer coefficient w m2.

Thermal coefficient expansion of marble.

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. Temperature is a monotonic function of the average molecular kinetic energy of a substance. 0 9 to 1 2 x 10 5. The coefficient of linear thermal expansion clte of any material is the change of a material s dimension per unit change in temperature.
