What Will Happen If You Cut A Hole In A Metal Sheet Then Heat It?

MetalMaster (admin) — Tue, 23 Feb 2010 01:45:13 +0000

We know that metal expands when heated, so what will happen if you cut a hole the size of a quarter in the center of a cookie sheet, then pop it in the oven until it’s very hot? Will a quarter still fit in the hole? Will the hole be bigger or small and why?
Thanks!
