Ball and ring experiment

This experiment is a volume expansion demonstration that shows that a ball is able to pass through a ring in a cold temperature but when the ball is heated using a Bunsen burner, the ball is unable to pass the ring. The equipment you will need for this experiment include:

  • Beaker with water
  • Bunsen burner
  • Ball and ring apparatus
     

Method and observations:

  • Hold the ball over the flame for a few seconds, rotating it, and then pass the ball through the ring
  • Place the ball over the flame again for a few seconds, rotating it. You will see than now the ball can’t go through the ring
  • Place the ball inside the beaker with water and now try to pass the ball through the ring. You will see that now the ball can pass through the ring
