Answer:
diameter of the hole increases .
Explanation:
In this case , the square sheet with hole will expand as if it had no hole .
A hollow sphere will expand to the same extent that a solid sphere expands .If we assume no hole in the square sheet of copper , the distance between two extreme point on the diameter will increase . It will increase even if circular hole is present . Hence diameter of the hole will increase.
Answer:
increases
Explanation:
When an object is heated, it expands.
When the object expands linearly, it is called linear expansion.
When the area of the object increases, it is called areal expansion.
When a hole is heated, then the area of hole increases, and then the diameter of hole also increases.
