Review

Experiment shows that if the temperature change $\Delta{t}$ of a solid object is not too great, the change in each dimension of the object is proportional to $\Delta{t}$ . In particular, if a solid object initially has length $L_0$ , the change $\Delta{L}$ in its length when the temperature changes by $\Delta{t}$ is

The quantity $\alpha$ (Greek letter alpha) in Equation 14-18 is called the $\textbf{coefficient of linear expansion}$ . It depends on what the object is made of, but not on the shape or size of the object.
