Problem

10.8 A hole is drilled in a copper sheet. The diameter of the hole is 4.24 cm at

27.0^{\circ} \mathrm{C}

. What is the change in the diameter of the hole when the sheet is heated to

227^{\circ} \mathrm{C}

? Coefficient of linear expansion of copper

=1.70 \times 10^{-5} \mathrm{~K}^{-1}
