a) A gold filling, with a coefficient of linear expansion of 1.4x10-5 °C1. The coefficient of linear expansion of tooth enamel is 1.6x10-5 °C¹. The void is filled at a temperature of 60 °C, and the volume is 55 cubic mm. By what amount does the volume of the gold decrease when it has cooled to 30°C in mm³? __mm³ AV=VBAT where B=3a b) By what amount does the volume of the void decrease when it has cooled to 30°C in mm³? __mm³ a) A gold filling, with a coefficient of linear expansion of 1.4x10-5 °C1.
