In olden days, while laying the rails for trains, small gaps used to be left between the rail sections to allow for thermal expansion. Suppose the rails are laid at room temperature $27 ^\circ\ C$. If maximum temperature in the region is $45 ^\circ\ C$ and the length of each rail section is $10\ m$, what should be the gap left given that $\alpha = 1.2 \times 10^{-5} K^{-1}$​​​​​​​ for the material of the rail section?
