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
. Then, the variation in heigth will be equal to:
