About This Product
With the ball and ring at the same temperature, the ball passes easily through the ring. The ball is then heated in a flame and expands due to increased molecular motion, so it will no longer pass through. The set is used in teaching heat, temperature and thermodynamics. The Ball and Ring Expansion Set Standard is available for supply within the United Kingdom and for export to United States, Zimbabwe, Uganda, Oman, South Africa and Laos.
