What is the difference between the molecules of a HOT soup in the pot and the molecules of the soup in the freezer?

• The molecules of the soup in the pot are moving and the molecules of the soup in the freezer are not moving.

• The molecules of the soup in the pot are moving faster than the molecules of the soup in the freezer.

• There is no difference because all of the soup is made of the same type of molecules.

• The molecules of the soup in the freezer are smaller than the molecules of the soup in the pot.
