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:
- Make sure that you have all apparatuses in the table above.
Cautions, Warnings, or Safety Concerns:
- Beware of the burner and the liquid nitrogen.
Discussion:
The bimetallic strip consists of brass and stainless steel. Since brass has higher thermal expansion coefficient than stainless steel. When it is heated by the burner, it bends to the stainless steel side. On the other hand, placed it in liquid nitrogen (77K) the strip bends in opposite which is to the brass side.
