Question 1

Everything in the world is made of atoms that vibrate.

1. What would happen to the atoms of a door if it was heated up?
2. What would happen to the atoms of a spoon if it was cooled down?

Answer 1

1. The door’s atoms would vibrate faster (also, the door may get a tiny bit bigger)
2. The spoon’s atoms would vibrate slower (also, the spoon will get a tiny bit smaller)
