Set-Up of the Data Collection System:
Part 1: Boyle's Law
1. Start a new experiment on the data collection system.
2. Connect the absolute pressure sensor to the data collection system using a sensor extension cable.
3. Put a drop of glycerin on the barbed end of a quick-release connector and put that end into one end of a short piece (about 2.5 cm) of plastic tubing that comes with the sensor.
4. Put a drop of glycerin on the end of the syringe. Connect the end of the syringe to the other end of the small piece of plastic tubing.
5. Adjust the plunger so there is 60.0 mL of air in the syringe.
6. Align the quick-release connector to the end of the plastic tubing with the pressure port of the absolute pressure sensor. Push the connector onto the port, and then turn the connector clockwise until it clicks (about one-eighth turn).
7. Configure the data collection system to manually collect pressure and volume. Define "volume" as a manually entered data set with units of milliliters.
8. Change the units of pressure measurement to Pa.
9. Start a new, manually sampled data set.
Part 2: Gay-Lussac's Law
1. Start a new experiment on the data collection system.
2. Display Pressure on the y-axis and Temperature on the x-axis (change the units of the temperature measurement to Kelvin).
3. Place the barbed connector of the pressure sensor tightly into one hole of the rubber stopper and connect it to the pressure port of the sensor with a piece of tubing. Use a drop of glycerin if necessary.
4. Insert the temperature sensor into the other hole in the rubber stopper. If necessary, add a drop of glycerin. Wrap the 250-mL flask 15 to 20 times with electric tape if available.
5. Set a 1500-mL beaker, 3/4 full with water, on the hot plate with a magnetic stirrer on the ring stand.
6. Place the stirring bar in the beaker.
7. Mount the 250-mL Erlenmeyer flask in the water so that it is covered with water as much as possible.
8. Place the stopper tightly into the Erlenmeyer flask.
9. Connect the pressure sensor and the temperature sensor to the data collection system.
10. Start recording data.
