Franklin’s Flask
- Demonstrate Boiling at a Reduced Temperature and Pressure.
Initially, the flask should be in a normal upright position and partially
filled with water. After bringing the water to a boil, close off the neck
with a rubber stopper fitted with a thermometer and invert the flask. Place
ice in the concave bottom. Water should start to boil again, and continue
to boil until it is only 15° or 20° above room temperature. - Located in L02, section C3.
