$\Delta V=\gamma \cdot V \cdot \Delta T$

$\Delta V=3 \alpha \cdot V \cdot \Delta T$

$\Delta V=3 	imes 23 	imes 10^{-6} 	imes \frac{4}{3} \pi 	imes(10)^{3} 	imes(100-0)$

$\Delta V=28.9 \;cm ^{3}$

$\Delta V=28.9\; cc$

An aluminium sphere of $20 \;cm$ diameter is heated from $0^{\circ} C$ to $100^{\circ} C$. Its volume changes by (given that coefficient of linear expansion for aluminium $\alpha_{A l}=23 \times 10^{-6}\;/{^o}C$
