Important Setup Notes:
This demonstration requires a supply of methane gas usually provided by the red and white gas carts found in rooms 2103, 2241, (and 2223 upon request).
Setup and Procedure:
To light the burner, connect the attached gas hose to the gas out (red panel) on the red and white gas cart.
- Open the gas valve.
- Light a match and bring it near the top of the burner.
- The flame will ignite the gas. Adjust the flame height accordingly by adjusting the valve.
- Show that the ball can get through the ring.
- Heat the ball by the burner. It may take a lot of time, so just put it on the iron ring tripod and heat it.
- Then Put the ball over the ring. This time the ball should cannot get through the ring.
Cautions, Warnings, or Safety Concerns:
- Always use the gloves and safety glasses throughout this demonstration.
- Beware of the heated plate - contact with skin could cause severe burns!
Discussion:
This demonstration show the thermal expansion property of the material which is the tendency of matter to change volume corresponding to the temperature changes.
