SpletThis physics video tutorial explains the concept of thermal expansion such as the linear expansion of solids such as metals and the volume contraction of liquids like water. It discusses the... SpletThe linear coefficient of thermal expansion (α) describes the relative change in length of a material per degree temperature change. As shown in the following equation, a is the ratio of change in length (Δl) to the total starting length (l i) and change in temperature (ΔT). By rearranging this equation, it can be seen that if the linear ...
