1.The height of the Washington Monument is measured to be 170 m on a day when the temperature is 35.0 °C. What will its height be on a day when the temperature falls to -10.0 ° C? Although the monument is made of limestone, assume that its thermal coefficient of expansion is the same as marble's.

1.The height of the Washington Monument is measured to be 170 m on a day when the temperature is 35.0 °C. What will its height be on a day when the temperature falls to -10.0 ° C? Although the monument is made of limestone, assume that its thermal coefficient of expansion is the same as marble's. 2.How much taller does the Eiffel Tower become at the end of a day when the temperature has increased by 15 ° C? Its original height is 321 m and you can assume it is made of steel. 3.What is the change in length of a 3.00-cm-long column of mercury if its temperature changes from 37.0 ° C to 40.0 ° C, assuming the mercury is unconstrained? 4.How large an expansion gap should be left between steel railroad rails if they may reach a maximum temperature 35.0 ° C greater than when they were laid? Their original length is 10.0 m
