Important Setup Notes:
- N/A
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.
Cautions, Warnings, or Safety Concerns:
- Beware of the heated rods - they can cause serious burns!
- Wear the safety grove and glasses.
Discussion:
This demonstration show that different materials have different [http://en.wikipedia.org/wiki/Coefficient_of_thermal_expansion coefficient of thermal expansion]. Once you choose a rod and place it on the holder, turn on the gas source to heat the rod. You will see that the orange tip scale will move to the left at some amount of rate. Then choose other rod in place of the previous one and heat it. The orange tip will move to the left at different rate.
