Set up for Thermal Conductivity Demo
Set up for Thermal Conductivity Demo
(Unit with 5 Fingers - Iron, Aluminum, Brass, Stainless Steel, Copper)

 

Code Number: 4B30.10

Demo Title: Thermal Conductivity Demo

Condition: Good

Principle: Thermal Conductivity

Area of Study: Thermodynamics

Equipment: 

Thermal Conductivity Demo (Unit with 5 Fingers - Iron, Aluminum, Brass, Stainless Steel, Copper), Digital Thermometers (5), Candles (Assorted), Gloves, Bunsen Burner, and Grill Lighter.

Procedure:

There are enough digital thermometers to put one on each finger or candles may be used in their place.  Heat the center with a Bunsen burner and observe the different conductivities.  The copper should be first followed by aluminum, brass, iron, and the stainless steel should not even be warm to the touch even after minutes of heating.

Bring some water to near boiling and dip only the ends of the four conducting bars into the water.
