Boyle's Law

When the temperature remains constant, how does the pressure of a gas in a rigid container change as the volume changes?

As volume increases, pressure decreases. Enlarge graph

Lab Summary:

In this activity, students will use an absolute pressure sensor to investigate the relationship of the pressure and volume of a gas at a constant temperature (Boyle’s Law).

Method:

Use an Absolute Pressure Sensor to measure the pressure change when a sample of gas is compressed and then expands.

Probeware

PASPORT Absolute Pressure Sensor (PS-2107)
Xplorer GLX Graphing Datalogger (PS-2002)
(or alternate PASPORT interface -- see other options)

Other Materials

Glycerin, C₃H₅(OH)₃

Pressure increases as temperature of gas rises. Enlarge image

Lab Summary:

In this exploration, the Chemistry Sensor will be used to observe the change in the vapor pressure of a liquid as the temperature varies. This information will then be related to the strength of intermolecular forces.
