Explanation:
It is defined as the increase in area per unit original area at 0∘C per unit rise in temperature. Coefficient of cubical expansion of solids: Similarly in volume expansion due to heating, the change in volume is directly proportional to the original volume and also the change in temperature, that is, ⇒V−V0∝V0Δt
