PIRA Code(s): 2B30.30 Set up time:3 minutes Operation: Place the two halves together. Put the vacuum pump on the valve and evacuate the air inside. Try to separate the pieces. Vacuum pump not included; it must be obtained from demo 3B30.30. Physics and Science Concepts: Fluid Mechanics, Statics of Fluids Safety: None
PIRA Code(s): 4A30.10 Set up time:1 minute Operation: Use a Bunsen burner to heat a bimetal strip and it will bend Physics and Science Concepts: Thermodynamics, Thermal Properties of Matter, Thermal Expansion Safety: Use caution when dealing with the Bunsen burner. Bunsen burner not included.
PIRA Code(s): 4A30.20 Set up time:2 minutes Operation: Try putting the ring around the ball. At room temperature the ring is slightly larger than the ball. Heat the ball over a Bunsen burner and it will no longer fit through the ring. Physics and Science Concepts: Thermodynamics, Thermal Properties of Matter, Thermal Expansion Safety: Use caution when using a Bunsen burner. The Bunsen burner is not included in the experiment.
