Behavior of Gases and Absolute Zero Determination Essay Example
Pre Lab Report Behavior of Gases and Absolute Zero Determination
Lab 4

Summary of Concepts:
Through this experiment we will be investigating the differences between the gas laws. We will investigate the relationships between pressure, volume, and temperature. By the end of the experiment we will have data to prove the gas laws.
The Gas Laws we will be investigating are as follows:
Boyle’s Law:
PV=C
Charles’ Law:
V/T=C
Gay-Lussac’s Law:
P/T=C
V/n=C
Ideal Gas law:
PV=nRT

Experimental Procedure:
PART 1: Pressure and Volume
1. Position the piston of a plastic 20 mL syringe at 10 mL. Attach the syringe to the valve of the Gas Pressure Sensor, as shown in Figure 1. A gentle half turn should connect the syringe to the sensor securely. Note: Read the volume at the front edge of the inside black ring on the piston of the syringe, as indicated by the arrow in Figure 1.
2. Connect the Gas Pressure Sensor to LabQuest and choose New from the File menu.
3. Set up the data-collection mode.
a. Change the data-collection mode to Events with Entry.
b. Enter Name (Volume) and Units (mL). Select OK.
4. Start data collection.
a. When the pressure reading has

The purpose of this lab is to demonstrate the ideal gas law under ordinary conditions. In this lab, the variables in the ideal gas law are known or can be found aside from the constant R. Thus, the R values can be found and relatively determine the relevancy of the ideal gas law to the lab conditions. The ideal gas law was tested using the reaction:…

The steps for this is firstly remove the calibration strip from the plastic bag, put the calibration strip into the strip inlet in the test meter, a beep will go off and 888 will appear on the screen. After 2 seconds another beep will go off and function number will on the screen, make that the number that appears matches the number printed on the box and finally put the calibration strip back in the plastic bag. For the rest of the equipment set up it is the same as the VO2 Max Test. In the VO2 Max Test it is explained how to approach this test by doing a PAR Q with the client, measuring the height and weight. Also the equipment is the exact same as the VO2 max test as calibration needs to be done on the mass flow sensor, gas analysers, ECG leads and the mouth piece and nose clips are used in the blood lactate test. Next write the information for the test into the computer which is the warm up time and the workload that is being used. Before the test begins let the client rest on the bike for a minute to get comfortable with the equipment and also to take the clients blood lactate level at rest. After the minute rest the warm up will begin and then the client will go into the exercise test where the workload will be added to the bike. The workload will increase through the test and every 2 minutes in the exercise test the…
