The Science of Heat Tweet. On a hot summer day, telephone wires sag between the poles that hold them up. Yet, on a cold day, the wires are tightly stretched. The reason is that most substances expand as they get hotter, and contract, or shrink, as they cool down. Metals, when heated, expand more than other kinds of solids do. Because of this, engineers have to be especially careful when designing and building large metal structures. For example, narrow gaps must be left between railroad tracks at regular intervals. This prevents the tracks from buckling during hot weather.
