Boiling As A Cooling Effect

Jon Asbornsen, of the Hawken School (Gates Mills, OH), shared his work on a novel twist to a time-honored demonstration of boiling points that uses LabQuest, a Gas Pressure Sensor, and a Temperature Probe. In the demonstration, a small volume of water is placed in a bell jar. As the air in the jar is evacuated, the water boils. Asbornsen measured the pressure and temperature inside the bell jar. The graph of his data tells the story more convincingly than mere observation of the phenomenon.
