Introduction: In this experiment we will conduct a set of experiment, each of illustrate a gas law. Then, gather data to identify the gas law described by each activity. Complete the calculations necessary to evaluate the gas law in each activity. From our results, derive a single mathematical relationship that relates pressure, volume, and temperature. As we expected our result was vary. Experimental Procedure: Make sure to review all the parts before you start the lab we will determine best way to conduct the testing.
And we will find out the relationship between the two of the four possible variable. Part One: Pressure and Volume Position the piston of a plastic 20 mL syringe at 10 mL. Attach the syringe to the valve of the Gas Pressure Sensor. A gentle half turn should connect the syringe to the sensor securely. And connect the Gas Pressure Sensor to LabQuest and choose New from the File menu. Set up the data- collection mode. Start data collection, then When the pressure reading has stabilized, select Keep and enter the volume in mL.
Stop data collection when you have finished collecting data to view a graph of pressure vs. volume. Part Two: Pressure and Temperature In this experiment, we will study the relationship between temperature of a gas sample and the pressure it exerts. we will place an Erlenmeyer flask containing an air sample in a water bath and you will vary the temperature of the water bath. Connect the Temperature Probe to Channel 2 of LabQuest. Then, Make sure the rubber stopper and flask neck are dry, then twist and push hard on the rubber stopper to ensure a tight fit.
