A rectangular metal block of volume 10\(^{-6}\)m\(^3\) at 273k is heated to 573k. If its coefficient of linear expansion is 1.2 x 10\(^{-5}\)k\(^{-1}\), the percentage change of it volume is

3a = Δv/vΔt
Δv/v = 3a × ΔΘ
= 3 × 1.2 × 10-5 × (573 - 273)
= 3 × 1.2 × 10-5 × 300
= 0.0108
(Δv/v) × 100 = 0.0108 × 100

Δv is 1.08 x 10⁻⁸ not 1.08 x 10⁻⁷. It might confuse some people.
