Thermal Properties of Matter

146528 A rod of silver at $0^{\circ} \mathrm{C}$ is heated to $100^{\circ} \mathrm{C}$. Its length is increased by $0.19 \mathrm{~cm}$. Coefficient of cubical expansion of the silver rod is

1 $5.7 \times 10^{-5} /{ }^{\circ} \mathrm{C}$
2 $0.63 \times 10^{-5} /{ }^{\circ} \mathrm{C}$
3 $1.9 \times 10^{-5} /{ }^{\circ} \mathrm{C}$
4 $16.1 \times 10^{-5} /{ }^{\circ} \mathrm{C}$
