AI Thread Summary
When a copper square is heated uniformly, it expands due to thermal expansion, leading to a larger area. Most participants agree that the square will become larger, supporting option a. However, confusion arises regarding whether the question pertains to the square itself or the hole left in the copper sheet after cutting. This ambiguity affects the interpretation of the results. Overall, the consensus leans towards the square expanding uniformly.

I agree with a. A square heated uniformly should just get uniformly larger.

Well now, wait a minute. Do they mean the copper square that got cut out, or the hole left in the sheet when the square was cut out? If the latter, then I'm not sure what the answer is...
