E)none of the above.

Question

Quizplus · Accepted Answer

The coefficient of thermal expansion (a) is the fractional change in length or volume of a material per unit change in temperature. It is defined as ΔL/LΔT or ΔV/VΔT, where L and V are the original length and volume, respectively, and T is the temperature. The unit of measure for a is therefore °C-1 or °F-1, as it represents the change in length or volume per unit temperature change.
