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): 4C33.50 Set up time:No setup required Operation: Hold one bulb in your hand so that it forces the liquid to enter the other bulb. Physics and Science Concepts: Change of State, Vapor Pressure Safety: Do not grasp too tightly as the glass may break.
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.
