The primary objective of this experiment is to determine the relationship between the pressure and volume of a
confined gas. The gas we will use is air, and it will be confined in a syringe connected to a Gas 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 the Gas Pressure Sensor. 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 graphs, you should be able to determine
what kind of mathematical relationship was first established by Robert Boyle in 1662 and has since been known
as Boyle’s Law.
In this experiment, you will
Use a Gas Pressure Sensor and a gas syringe to measure the pressure of an air sample at several different volumes. Determine the relationship between pressure and volume of a gas and describe that relationship with a mathematical equation Use LoggerPro software to collect data, analyze the data, and create useful graphs to interpret the data.

The initial screen in Logger Pro should tell you several things:
If the device is detected and which probe is connected o If the “Device not Detected” error message appears instead of an output reading, check all of the cable connections to the LabPro and the laptop. You may need to connect to a different USB port or reconnect the power cable. The default collection settings o For the Gas Pressure Sensor the default settings are Volume (mL) and Pressure (kPa) The output reading from the probe
Click on the LabPro icon
Click on the picture of the Gas Pressure Sensor
Choose the unit of “atm” from the menu
From the Data menu, choose “New Calculated Column”
In the pop-up box, Type in the “Name” and “Short Name” for the calculation
In the “Expression” box, type in your equation. o You must click on the “Variables (Columns)” button in order to choose the variables in your expression
Repeat the entire process for the second calculated column
Follow the above procedure, to create another calculated column for “Inverse Volume” Be sure to include the units
When a new graph is inserted, use the “Graph Options” menu to make changes to the graph
When a new graph is inserted, LoggerPro will automatically choose the last column in the data table. You will
need to change both the data set being plotted on the y-axis, and the data set being plotted on the x-axis.
From the Insert menu, choose “Graph” Right click the cursor inside the graph, a pop-up menu should appear, choose “Graph Options” Graph Options Tab – this is where you can title your graph
Select the “Axes Options” Tab
In the “Y-Axis Columns”, checkmark next to Pressure and uncheck “Inverse Volume”
In the “X-Axis” box, choose “Inverse Volume” from the drop down menu.
Click “Done”
