A rectangular metal block of volume 10-6m3 at 273k is heated to 573k. If its coefficient of linear expansion is 1.2 x 10-5k-1, the percentage change of it volume is

1.5%

1.1%

0.4%

0.1%

Answer Details

Y =

\frac{Δ V}{V \times Δ θ}

3 x 10-5 x 1.2 = $\frac{Δ V}{10^{- 6} \times (573 - 273)}$

$Δ$ V = 1080 x 10-11m3

% $Δ$ V = $\frac{1080 \times 10}{10^{- 6}}$ x 100

= 1.08%

$\approx$ = 1.1%
