Introduction
The PASCO SE-9790 Student Bell Jar
demonstrates the effect of air pressure on the
boiling point of a liquid, on the size of a balloon,
on the size of a marshmallow, and on the holding
power of a suction cup. It also demonstrates that
air has mass.
The syringe and one-way check valve system
constitute an inexpensive vacuum pump.
An extra connector is provided to permit the
Student Bell Jar to be connected to a PASCO
Pressure Sensor (Absolute, CI-6532 or
Differential, CI-6533), allowing the monitoring of
the pressure inside the chamber.
