The height of the Washington Monument is measured to be 170 m on
a day when its temperature is 35.0°C. What will the change in its
height be on a day when its temperature falls to −3.9°C? Although
the monument is made of limestone, take the thermal coefficient of
expansion to be the same as for marble, which is 2.50 10^-6/°C. (Be sure to include the
appropriate sign with your answer.)
