Equipment:

Method:

Part 1: Boyle's Law

Gathered all equipment and materials. Inspected all equipment for damage or contamination. Hotplate/Magnetic Plate/Stand was already assembled.
Set up data collection system. Assembled GLX, and attached all sensors.
Set up automatic titrator, and attached modified syringe. Connected to GLX.
Adjusted syringe, so that it would contain 60 mL of air. Configured GLX to measure pressure in Pascals. Measured atmospheric pressure within syringe.
Began compressing the syringe, using the automatic titrator, so as to ensure a steady reading.
Prepared graph, ending experiment once syringe was compressed to its minimum size.
Saved data, and returned all data to its point of origin, save for the GLX, the pressure sensor, and the tubing used.

Part 2: Guy-Lussac's Law

Gathered all equipment and materials. Inspected all equipment for damage or contamination.
Started a new experiment on the data collection system.
Assembled the 2-hole rubber stopper, inserting the pressure sensor's tube, and fitting the stopper into the end of the cylindrical metal container and inserting the stainless steel temperature sensor into the free hole.
Filled the 1500-mL with 1125 ml of water, before placing the filled container on the Hot Plate/Magnetic Stirrer/Stand, and inserting the stir bar.
Mounted the cylindrical metal container with sensors into the beaker, ensuring that it is covered with as much water as possible, without adding more.
Attached the sensors to the GLX, activated the magnetic stirrer, and began recording data.
Turned on the hot plate, monitoring the temperature until the water bath reached 80º C.
