Experiment    6 Boyle’s Law:  Pressure-Volume Relationship in Gases The primary objective of this experiment is to determine the relationship between the pressure and volume of a confined gas. The gas we use will be air, and it will be confined in a syringe connected to a pressure sensor (see Figure 1). When the volume of the syringe is changed by moving the piston, a change occurs in the pressure exerted by the confined gas. This pressure change will be monitored using a pressure sensor connected to a CBL System and a TI-82 Graphing Calculator. It is assumed that temperature will be constant throughout the experiment. Pressure and volume data pairs will be collected during this experiment and then analyzed. From the data and graph, you should be able to determine what kind of mathematical relationship exists between the pressure and volume of the confined gas. Historically, this relationship was first established by Robert Boyle in 1662 and has since been known as Boyle’s law.

Prepare the pressure sensor and an air sample for data collection. • Plug the pressure sensor into the adapter cable in Channel 1 of the CBL. • Connect the CBL System to the TI-82 calculator with the link cable using the port located on the bottom edge of each unit. Firmly press in the cable ends. • Move the piston of the syringe until the front edge of the
