thermal expansion

Physics

See expansivity.

Chemical Engineering

The increase in volume of a substance with temperature. Most substances increase in volume with increasing temperature. The coefficient of expansion, α, is the ratio of the change in length of a substance with temperature to the length at 0^ºC. The (p. 376) coefficient of volumetric expansion, β, is approximately three times the value of α. Water is a notable exception in which above 0^ºC, the volume decreases with temperature to approximately 4^ºC and increases in volume thereafter. The SI unit is K⁻¹.

Geography

The rupturing of rocks and minerals mainly as the result of large daily temperature changes. The exterior of the rock expands more than the interior. Whether thermal expansion is effective in an environment with no water is open to question; see Koch and Siegesmund (2002) Spec. Publ. Geol. Soc. Lond. 205. See also Smith et al. (2005) Geomorph. 67, 1–2 and Wigley and Raper (1987) Nature 357 on the thermal expansion of sea water associated with global warming.
