I4-11: BOILING AT REDUCED PRESSURE
Additional Info
- ID Code: I4-11
- Purpose: Demonstrate that water boils at a lower temperature under reduced pressure.
- Description: Water is boiled in the flask, then heat is removed and the flask is sealed after boiling ceases. Dry ice is packed around the flask, reducing the pressure inside the flask. The boiling immediately resumes.
- Availability: Available
- References: REFERENCES: (PIRA 4C30.10)
- Loc codes: I4, I0
