Activity Question

 Question:

Why does a metal lid on a glass jar open more easily when we pour hot water on it?

 

Activity Response

Answer:

When we pour hot water on the metal lid, the heat causes the metal to expand more than the glass jar. As the lid expands, it becomes slightly loose, making it easier to open. This shows that materials expand when heated and contract when cooled.
