Heat a material and it expands: ΔL = α·L·ΔT, where α is the coefficient of linear expansion. Area grows at twice that rate and volume at three times. It is why bridges have expansion joints, why rails buckle in heat, and why Invar — with almost zero expansion — is prized for precision instruments.

α23 µm/m·°C

Length change11.5 mm

Area change0.230 m²

Volume change3.450 m³

Governing equation

Δ L = α L_{0} Δ T = (23 \times 1 0^{- 6}) (10) (50) = 11.5 mm

Reading this result: Heating 10 m of Aluminum by 50°C stretches it about 11.5 mm; area and volume grow 2× and 3× as fast.
