Thermal Expansion

  • Rolf E. Hummel


The length L of a rod increases with increasing temperature. Experiments have shown that in a relatively wide temperature range the linear expansion ΔL is proportional to the increase in temperature ΔT. The proportionality constant is called the coefficient of linear expansion α L . The observations can be summarized in
$$\frac{{\Delta L}}{L} = {\alpha _L}\Delta T$$
