if i have a metal sheet and i cut a hole in its center, and heat the sheet, will the hole grow larger or smaller?? (knowing that the material has a positive therml expansion)?
i know that the metal wants to expand, but in which direction,
??
i would think it would grow smaller but that's just intuition. can someone please explain this to me
