If you drill a hole in a metal plate and then freeze the plate, does the hole get smaller, bigger or stays the same?
gpt
Reduce the plate to just the material around the hole. That material will contract, shortening the length (circumference). Therefore the hole will get smaller.

If the whole object didn't behave the same way, there would be tremendous forces generated as the bulk material pulled away from the material right around the hole, and we'd see weaker materials actually separating under these conditions. We don't. (There are other ways to prove the whole - heh - acts like the hole lining does.)
