Thermal Expansion Encyclopedia.com

THERMAL EXPANSION. CONCEPT. Most materials are subject to thermal expansion: a tendency to expand when heated, and to contract when cooled. For this reason, bridges are built with metal expansion joints, so that they can expand and contract without causing faults in the overall structure of the bridge.
