The Eiffel Tower can be 15 cm taller during the summer
The Eiffel Tower can be 15 cm taller during the summer because the metal structure expands when heated by the sun. As temperatures rise, the iron atoms vibrate more and take up additional space, causing the tower to grow slightly in height. This fascinating fact highlights how thermal expansion affects even massive landmarks, making it seem almost unbelievable but entirely true.

❓ Frequently Asked Questions
Why can the Eiffel Tower be taller in summer?
Metals expand when heated; the iron structure lengthens slightly as temperatures rise, making the tower taller.
How much taller can it get in hot weather?
About 15 cm (0.15 m) taller, depending on how hot it gets and other conditions.
Does every part of the tower expand the same way?
Not exactly. Different parts and joints may expand by different amounts, but the overall height still increases with temperature.
What science concept explains this effect?
Thermal expansion — materials expand when heated. The change is described by the coefficient of linear expansion for the material.
