coefficient of expansion

January 2005
Hutchinson Dictionary of Scientific Biography;2005, p1
coefficient of exQuantity that describes the amount of expansion undergone by a material for a degree rise in temperature. It is expressed as the increase in length per unit length, per degree centigrade. For example, the metal with the lowest coefficient of expansion is Invar, at 2.3 × 10-6 m of expansion for every meter in length, per degree Celsius rise in temperature.
