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.
PIRA Code(s): 4E30.10 Set up time:5 minutes Operation: Fill sphere with water and submerge in buckets of water or liquid nitrogen at different temperatures. Dewar of liquid nitrogen and bucket can be obtained in the physics machine shop. Physics and Science Concepts: Gas Laws, Thermodynamics Safety: Always wear protective clothing when handling liquid nitrogen.
