How much taller (in m) does the Eiffel Tower become at the end of a day when the temperature has increased by 17°C? Its original height is 324 m and you can assume it is made of steel.

324.066096 m.

Explanation:

Given that

height of the tower ,h= 324 m

The increase in temperature ,ΔT = 17°C

We know that coefficient of thermal expansion for steel ,α= 12 x 10⁻⁶ C⁻¹

The increase in height is given as

Δ h = α h ΔT

Now by putting the values in the above equation we get

Δ h= 12 x 10⁻⁶ x 324 x 17 m

Δ h=66096 x 10⁻⁶ m

Δ h=0.066096 m

Therefore the height of the tower become 324.066096 m.
