1 EXPERIMENT 12 GAS LAWS ( BOYLE S AND GAY-LUSSAC S LAW) INTRODUCTION: In order to specify fully the condition of a gas it is necessary to know its pressure, volume, and temperature. This quantities are interrelated, being connected by the general gas law, so that if any two of them are known, the third is determined by the mathematical relation between them. One of the important properties of a gas is that it always tends to expand until it completely fills the vessel in which it is placed, and thus the pressure it exerts depends on the volume it occupies. To describe fully the condition of a gas it is necessary to give not only the volume but also the temperature and pressure, because they are all interrelated. The purpose of this experiment is to study two of the gas laws; that is, to develop the relation between the volume and the total pressure of a given mass of gas when the temperature is kept constant; and to investigate the variation of the pressure, of a given mass, of gas with changes in its temperature, when the volume is kept constant. the volume to the pressure, and the pressure to the temperature. THEORY In studying the behaviour of a gas under different conditions of pressure, temperature, and volume, it is convenient to keep one of these constant and to vary the other two. Thus, if the temperature is kept constant, one obtains the relation between the pressure and the volume; if the volume is kept constant, one gets the relation between the temperature and the pressure. Boyl s law: if the temperature is kept constant, the volume of a given mass of gas varies inversely as the pressure. This means that for a constant temperature, the product of the volume and the pressure of a given amount of gas is constant. Thus (Eq. 1) PV = constant or P 1 V 1 = P 2 V 2, where V 1 is the volume of a given mass of gas at pressure P 1, and V 2 is the volume at pressure P 2. The experimental test of Boyl s law consists in observing a series of different volumes, measuring the corresponding pressures, and observing how nearly constant the product of the two remains. GAY-LUSSAC LAW: if the volume remains constant, the pressure of a container of a gas is directly proportional to its absolute temperature. THE EXPERIMENT: 1. EXPERIMENTAL APPARATUS: To demonstrate the concept of BOYL S LAW (pressure vs. volume) and GAY- LUSSAC S LAW (pressure vs. absolute temperature) you will use the Pressure Sensor and the

2 temperature Probe with the Vernier Logger Pro Software and its Interface (Lab Pro). You will also find your laboratory station equipped with an Erlenmeyer flask, beaker, and heating plate. 1. EXPERIMENTAL PROCEDURE: The white stem on the end of the Gas Pressure Sensor Box has a small threaded end called a luer lock. With a gentle half turn, you may attach the plastic tubing to this stem using one of the connectors already mounted on both ends of the tubing. The Luer connector at the other end of the plastic tubing can then be connected to one of the stems on the rubber stoppers that are supplied, as shown in figure 1. Figure 1 Figure 2 Figure 3 Preparing Logger Pro for Measurements A. Boyl s law experiment: Connect the Pressure Sensor into the LabPro interface's Ch.1; Open the LoggerPro application from the desktop. Set the syringe to 20 cc volume. Connect the 20mL plastic syringe directly to the stem, as shown in figure 3, to secure the connection twist the syringe with a gentle 1/2 turn. The pressure inside the syringe is now equal to atmospheric pressure at the selected volume. Open Boyle s Law file from Physics_Experiments folder Click the Collect button and monitor the pressure in the data table. Make sure that the pressure on the syringe keeps the volume at 20 cc while your are collecting the data. When this pressure has stabilized, read the volume on the syringe and click Keep button. A data entry box will appear allowing you to enter the volume of air in the syringe; in this box you should record the syringe volume in cc (i.e. 20). Decrease the volume to 15 cc and take a new pressure measurement. Again let the pressure stabilise before you click the Keep button. Collect the pressure for the volumes of 12 cc, 10 cc, and 7 cc by following the same procedure outlined in the previous steps.

4 Explain what the slope of the curve represents. QUESTIONS: 1- Explain what effect a change in temperature will have on the Boyle s law experiment. 2- What is the barometric pressure in Ifrane? Would you expect this value to be different than the barometric pressure in Rabat? Explain your reasoning.
