SUMMARY

When two boxes made of the same material and size are subjected to an equal temperature increase, their expansion behavior differs if one box has a hole. The discussion centers on a metal disk experiment where a small disk is removed from a larger ring after heating. The consensus is that the diameter of the remaining ring does not shrink after the small disk is removed, indicating that the expansion properties are influenced by the structural integrity of the material rather than just the presence of a hole.

PREREQUISITES
  • Thermal expansion principles
  • Material science fundamentals
  • Understanding of structural integrity
  • Basic thermodynamics
NEXT STEPS
  • Research the principles of thermal expansion in solids
  • Explore material properties affecting expansion, such as Young's modulus
  • Study the effects of structural changes on thermal behavior
  • Investigate practical applications of thermal expansion in engineering
USEFUL FOR

Students of physics, materials engineers, and professionals involved in thermal management and structural design will benefit from this discussion.

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.

Thanks a lot sir 😇
