1 PRESSURE-TEMPERATURE RELATIONSHIP IN GASES LAB PS2.PALM INTRODUCTION Gases are made up of molecules that are in constant motion and exert pressure when they collide with the walls of their container. The velocity and the number of collisions of these molecules is affected when the temperature of the gas increases or decreases. In this experiment, you will study the relationship between the temperature of a gas sample and the pressure it exerts. Using the apparatus shown in Figure 1, you will place an Erlenmeyer flask containing an air sample in water baths of varying temperature. The pressure inside the flask will be monitored with a Pressure Sensor and temperature will be monitored using a Temperature Probe. The volume of the gas sample and the number of molecules it contains will be kept constant. Pressure and temperature data pairs will be collected during the experiment and then analyzed. From the data and graph, you will determine what kind of mathematical relationship exists between the pressure and the absolute temperature of a confined gas. You may also do the extension exercise and use your data to find a value for absolute zero on the Celsius temperature scale. Figure 1 PURPOSE The purpose of this experiment is to determine the relationship between pressure and temperature for a gas, keeping the volume of the gas and the number of gas molecules constant. Reference: Adapted from lab supplied by Vernier Software & Technology. PS2.PALM-1
2 EQUIPMENT/MATERIALS LabPro interface with AC adapter Palm handheld with Data Pro Palm LabPro interface cable Vernier Gas Pressure Sensor with the following accessories: Plastic tubing with 2 connectors Rubber stopper assembly Vernier Temperature Probe Ice 125-mL Erlenmeyer flask 1 L Beaker 200 ml Graduated cylinder (2/class) For optional data collected at 100 C: Ring stand and utility clamp Hot plate Glove or cloth SAFETY Always wear an apron and goggles in the lab. Use caution handling the hot plate and boiling-water bath. PS2.PALM-2
3 PROCEDURE 1. Prepare the LabPro, Temperature Probe and Pressure Sensor for data collection: a. Plug the Temperature Probe into Channel 1 of the LabPro. b. Plug the Pressure Sensor into Channel 2 of the LabPro. c. Obtain a rubber-stopper assembly with a piece of heavy-wall plastic tubing connected to one of its two valves. Attach the connector at the free end of the plastic tubing to the Pressure Sensor with a clockwise turn. Leave the two-way valve on the rubber stopper open (lined up with the valve stem as shown in Figure 2) until Step 6f. d. Insert the rubber-stopper assembly into a 125-mL Figure 2 Erlenmeyer flask. Important: Twist the stopper into the neck of the flask to ensure a tight fit. Figure 3 e. Close the 2-way valve above the rubber stopper do this by turning the valve handle so it is perpendicular with the valve stem itself (as shown in Figure 3). The air sample to be studied is now confined in the flask. f. Connect the Vernier AC adapter to the LabPro and plug it in. After a few seconds, you should hear the happy tones of the Lab Pro. If not, make sure that the adapter is plugged in. 2. Remove the stylus from the right side of the handheld. Connect the handheld to the LabPro using the Palm LabPro interface cable. Firmly press in the cable ends. 3. Press the power button on the top right of the handheld to turn it on. To start Data Pro, tap the Data Pro icon on the Applications screen. Choose New from the Data Pro menu or tap to reset the program. PS2.PALM-3
4 4. On the Main screen of Data Pro, Tap. If the handheld displays TEMP(C) in CH1 and PRESS(KPA) in CH2, proceed directly to Step 6. If it does not, tell your teacher. 5. Set up the data-collection mode: a. While still on the setup screen, tap, then choose Selected Events. b. Tap to return to the Main screen. 6. Tap to begin data collection. Temperature readings (in C) and pressure readings (in kpa) are displayed on the handheld screen. 7. Collect pressure vs. temperature data for your gas sample. a. Place the flask into a 1 L beaker containing about 700 ml of cold water and some ice. Make sure the entire flask is covered with water (see Figure 3). Stir the bath. b. Place the Temperature Probe into the ice-water bath. c. When the temperature and pressure readings displayed on the screen have both stabilized, tap to store the temperature-pressure data pair. d. Remove the flask and the Temperature Probe from the water bath. 8. Repeat Step 8 using just 800 ml of cold tap water. 9. Repeat Step 8 using 800 ml of cool water. 10. Repeat Step 8 using 800 ml of room temperature water. 11. Repeat Step 8 using 800 ml of hot tap water. 12. Optional: Use a ring stand and utility clamp to suspend the Temperature Probe in a 1L beaker containing about 800 ml of boiling water. CAUTION: Do not burn yourself or the probe wires with the hot plate. To keep from burning your hand, hold the tubing of the flask using a glove or a cloth. After the Temperature Probe has been in the boiling water for a few seconds, place the flask into the boilingwater bath and repeat Step Tap to stop data collection, then tap on the Event Collection screen and a graph of all data vs. time will be displayed. PS2.PALM-4
5 14. Change the axis values so that a graph of pressure vs. temperature will be displayed, then examine the displayed graph: a. On the Graph screen, tap the x-axis label, and choose CH1: TEMP(C). b. Tap the y-axis label, and choose CH2: PRESS(KPA). c. Examine the data points along the displayed graph of pressure vs. temperature ( C). To examine the data pairs on the displayed graph, tap or any data point. As you move the examine line, the temperature and pressure values of each data point are displayed to the right of the graph. d. Record the data pairs in your data table. Round pressure to the nearest 0.1 kpa and temperature to the nearest 0.1 C. 15. Use the following steps to create a new column of Kelvin temperatures: a. On the Graph screen, tap. b. Tap on the Data screen. c. Enter the column name (Temp) and unit (K). d. Tap and choose the formula, X+A. e. Choose CH1: TEMP(C) as the Column for X, and enter a value of 273 for A. f. Tap to display the graph of pressure vs. Temp (K). g. Tap or any data point to move the examine line and record the Kelvin temperature values (displayed to the lower right of the graph) in your data table. 16. Follow this procedure to calculate regression statistics and to plot a best-fit regression line on your graph of pressure vs. temperature (K): a. On the Graph screen, tap, then tap. b. Choose CH2: PRESS(KPA) as the Data to Fit. c. Choose Linear as the Fit Equation. The linear-regression statistics for these two lists are displayed for the equation in the form: y = ax + b where x is temperature (K), y is pressure (kpa), a is a proportionality constant, and b is the y-intercept. Record the linear-regression for your experiment on your Data Sheet. d. To display the linear-regression curve on the graph of pressure vs. temperature (K), tap. 17. Optional: Print a graph pressure vs. Kelvin temperature (with a regression line displayed). PS2.PALM-5

In order to perform this experiment, what two experimental factors were kept constant? 2. Based on the data and graph that you obtained for this experiment, express in words the relationship between gas pressure and temperature. PS2.PALM-6
7 3. Explain this relationship using the concepts of molecular velocity and collisions of molecules. 4. Write an equation to express the relationship between pressure and temperature (K). Use the symbols P, T, and k. 5. Using the linear regression from step 16c above and assuming constant volume, what would the pressure of the air be at 40.0 C? 6. Use a 200 ml graduated cylinder to determine the volume of the Erlenmeyer flask when it is topped with the stopper used in this experiment. Use this volume, the ideal gas law, and your answer from Question 5 to determine the number of moles of gas in the Erlenmeyer flask during your experiment. (101.3 kpa = 1 atm) PS2.PALM-7
