4A30.55 - Expansion & Contraction Demo - Expansion Tube

Code Number:
Demo Title:
Expansion & Contraction Demo - Expansion Tube
Expansion & Contraction with Temperature Variation
Area of Study:
Heat & Fluids
Thermal Expansion Demo (Copper Tubes, Stand, Hoses), Micrometer (Dial).

The only critical thing here is to get the micrometer situated so that it operates properly.  The dial can be moved to zero on the micrometer before starting the demo.  Hot water may be run through from the hot water line but boiling water poured in through a funnel is probably more effective.  With the thumbscrew you are able to fix one end of the tube at any length desired (1/2 or 1 meter, 1/2 or 1 yard).
