Question

How much taller does the Eifel Tower become at the end of a day when the temperature has increased by 10°C? Its original height is 324 m and you can assume it is made of steel.

Answer 1

Answer:

Eifel Tower height will increase by 0.03888m

Explanation:

You can calculate the variation in height by using the coefficient of thermal expansion of the steel:

ΔH = H*α*ΔT

The coefficient of thermal expansion α is describes the change in length of an object after a change in temperature. the coefficient of thermal expansion of the steel depends on the composition of the steel, but in general, it has a value of around $12*10^{-6}oC^{-1}$. Then, the variation in heigth will be equal to:

$ΔH = H*α*ΔT = 324m *12*10^{-6}oC^{-1}*10oC = 0.0388m$
