A small amount of water is placed inside an airtight copper tube, with the end sealed by a rubber stopper. The tube is heated using a blowtorch, causing the water inside to boil. As the water changes from a liquid to a gas the pressure inside the tube increases. Eventually ...
An iron bar is used to try to pick up some paperclips or thumbtacks. It is not able to do this because it is not magnetized. The rod is placed in a long solenoid and DC power applied. The rod becomes magnetized and is able to pick up some of the ...
A bimetallic strip (12" ) of iron and aluminum is vertically fixed at one end to a board. The top end has a pointer that is free to move. The bimetallic strip is straight at room temperature. When heated with a blow torch, the strip curves due to differential expansion.
Helium introduced into a resonant cavity, including the lungs of the demonstrator, will increase the frequency of all pitches originating in the cavity.
