WebThe linear thermal expansion coefficient (CTE) is dependent on the material from which an object is made. Generally, linear thermal expansion is most applicable to solids. The CTE employs reciprocal temperature units (K-1, °F-1, °C-1, etc.) representing the length change per degree per unit length, e.g., in./in./°F or mm/mm/°C. The table at ... WebLinear thermal expansion applies mostly to solids. Knowing the initial length L 0 [m] of a given solid (e.g. metal rod), the temperature difference ΔT [ºC] and the coefficient of linear expansion of the solid α [1/ºC], the change in length ΔT [m] of the solid can be calculated as: \[\Delta L = \alpha \cdot L_0 \cdot \Delta T \tag{1}\] The change in length is directly … WebThe coefficient of thermal expansion is defined as the change in length or volume of a material for a unit change in temperature.
