Did you know the Eiffel Tower—yes, that well-known sign of Paris—grows taller by up to 15 cm in summer?
No, it is not magic. It is physics. The concept is called thermal expansion.

At DeclutterED, we like to show that science is not just in books. It is all around you, all the time. And when you see how, you do not forget.

In this blog, we will look at:

• Why the Eiffel Tower “grows”
• What thermal expansion is
• How this applies to daily life (and your tests)

If you want to do well in school or on tests like the GRE or GMAT, quality education in India starts by making science easy to get. Let’s go.

1. What is Thermal Expansion?

The Eiffel Tower is made of iron. Iron is a metal. Like most things, it expands when heated. In the summer, it can get very hot in Paris. When the iron in the tower gets hot, the small bits in it move more. This makes the iron get big. The tower gets tall.

The result? The 330-meter-tall tower can grow by about 15 centimeters!

This is thermal expansion in action.

The formula engineers use to calculate it is simple:

ΔL = α × L × ΔT

Where:

• ΔL = Change in length
• α = Coefficient of linear expansion
• L = Original length
• ΔT = Change in temperature

Don’t worry. This is not a test. But if you get the logic behind the formula, it can help you see how things in physics go together. You can do well on tests like the SAT, GRE, or JEE. And if you want the best GRE coaching in Hyderabad online that makes things this easy, we are here for you.

2. Real-World Examples of Thermal Expansion

The Eiffel Tower is not the only place you see thermal expansion. 

Here are some things you see in your day:

• Railway Tracks: Do you see small spaces between rails? The space is there so the rails can get big in the hot sun. This stops them from bending.
• Bridges: They have special joints so they can move. This is for when the heat goes up or down.
• Glass Jars: Can’t open a jar? Put hot water on top. The metal top gets a bit big and is easy to open.

We look at these things in our work at DeclutterED. Because science should make sense. You should not just say words you do not know. This is why our online coaching center is made for those who want to see things in a clear way.

3. Why This Matters for Students

You may ask, Why does this matter to me? Here is why:

• It is a good way to see an idea. When you know the ‘why’, you will not forget.
• Tests like the GRE or GMAT check if you can use ideas. They do not just check what you can say from memory.
• It helps you ask “why does this happen?”. This is key for science, for finding new things, and for life.

Many who come to us from Hyderabad and other places start with science. They stay for our best GMAT online coaching. This is because we show how ideas from one class fit with others. This is also why we have GRE coaching in Hyderabad. It is all about deep knowing, not just learning by heart.

The science of the big tower opens a door. You learn about heat, small bits, and why things get big. And you want to know more.

Conclusion: The World is a Science Lab—Just Look Around

The Eiffel Tower getting taller is not just a fun thing to know. It shows us that physics is all around. From hot train tracks to jar tops you can’t open, the ideas you learn in school are in your life.

That is what we do at DeclutterED—we make learning real, useful, and great fun.

So, next time you see steel bars where a new house is being made, or feel your hot car, think: “That’s thermal expansion at work.”And if you need an online coaching center that makes ideas like this come to life—for GRE coaching in Hyderabad, GMAT coaching in India, or basic science—you can start with DeclutterED.
