Question
The height of the Washington Monument is measured to be 170 m on a day when the temperature is $35.0^\circ\textrm{C}$. What will its height be on a day when the temperature falls to $-10.0^\circ\textrm{C}$? Although the monument is made of limestone, assume that its thermal coefficient of expansion is the same as marble’s.

$1.70\times 10^2 \textrm{ m}$. The decrease in height is negligible.
