Setup and Procedure:
Note: Make sure that one of the red & white gas cart are in placed and the gas hose is connected to the utility trench gas line. The gas cylinder that supplies the gas to utility trench gas line may or may not be connected/installed and should be inspected.
- 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.
