A metal cube of length \(10.0\;mm\) at \(0^\circ C\) is heated to \(200^\circ C\). Its coefficient of linear expansion is \(2 \times {10^{ - 5^\circ }}{C^{ - 1}}\). The percent change of its volume is
1 0.2
2 0.1
3 1.2
4 0.4
Explanation:
Percentage change in volume \(=\gamma t \times 100\) \(=3 \alpha t \times 100=300 \alpha t=300 \times 2 \times 10^{-5} \times 200=1.2\)

A solid ball of metal has a concentric spherical cavity with in it. If the ball is heated, the volume of the cavity will
1 Decrease
2 Increase
3 Remain unaffected
4 None of these
Explanation:
When the ball is heated, expansion of ball and cavity both occurs, hence volume of cavity increases.

Two holes of different radii \({r_1}\) and \({r_2}\left( {{r_1} > {r_2}} \right)\) are cut in a metal sheet. If the sheet is heated
1 Both \(r_{1}\) and \(r_{2}\) will decrease
2 \(r_{1}\) will increase, \(r_{2}\) will decrease
3 Both \(r_{1}\) and \(r_{2}\) will increase
4 \(r_{1}\) will decrease, \(r_{2}\) will increase
