Do two boxes expand equally with temperature if one has a Hole?

In summary, the conversation is discussing the expansion of two boxes of the same material and size, one with a hole, when heated to the same temperature. The example of a metal disk being cut into a small disk and a ring, and then heated, is used to explain the concept. The question is whether the diameter of the ring will shrink when the small disk is removed, and it is concluded that there will be no change.

Suppose we have two boxes of same material and same size but one have a hole in it and if we raise the temperature with equal amount then does two box expand equally?

Hi.
Interesting. Let me clear the idea you seem to have.
There is a metal disk. We cut it apart with a small disk and a ring part and keep them assembled.
We heat them up. The diameter of the disk grows. Then we take the small disk out. Does the diameter of the disk, now the ring, shrink ?

It seems no change to me.

FAQ: Do two boxes expand equally with temperature if one has a Hole?

1. Do both boxes expand equally with temperature?

Yes, both boxes will expand with temperature. This is a fundamental property of matter known as thermal expansion.

2. Will the box with a hole expand differently than the one without a hole?

Yes, the box with a hole will expand differently than the one without a hole. The presence of a hole will affect the distribution of heat and cause uneven expansion.

3. How does the size of the hole affect the expansion of the box?

The size of the hole will affect the expansion of the box. A larger hole will allow for more heat to escape, resulting in less expansion compared to a smaller hole.

4. Can the expansion of the boxes be predicted based on the size of the hole?

It is difficult to predict the exact amount of expansion based on the size of the hole. Other factors such as the material and thickness of the boxes will also play a role in their expansion.

5. What happens if the boxes are made of different materials?

If the boxes are made of different materials, they will expand at different rates due to their unique thermal properties. This can also affect the expansion of the boxes with a hole compared to the one without a hole.
