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
Avogadro’s Law
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
