Large Ball and Ring Stand, 4A30.20

Location:

Cabinet: Thermodynamics Cabinet
Bay: (A3)?
Shelf: #1?

Description:

This demonstration has a ball and ring with stand. It demonstrates the thermal expansion of the material by heating the ball.

Equipment	Location	ID Number

A ring with stand and a ball with hanger	TD, A3, Shelf #1	4A30.20
Burner with an iron ring tripod and wire net screen	location	NA
An iron ring tripod and a screen	location	NA
Safety grove and glasses	location	NA
Red and white gas carts	Rooms 2103, 2241, (and 2223 upon request)

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.
