Experiment #: 5
Title: Gas Laws
Purpose:
The purpose is to observe gas laws through different
experiments.
Procedure
Volume of syringer without weights: 33 mL
Boyle’s Law Experiment: Observe the inverse
(atmospheric pressure)
relationship of pressure and volume.
2.5 lbs: 27 mL
1. Place a capped fitted syringe into a base with a small
5 lbs: 22.5 mL
wooden platform placed on top of the plunger.
7.5 lbs: 18 mL
2. Observe the volume that is in the syringe with no
10 lbs: 16.5 mL
weight.
15 lbs: 13.0 mL
3. Add weight of 2.5 lbs. on platform and record the
volume.
The higher the pressure, the slower the volume start to

decrease.
5. Add another 2.5 and record the volume.
6. Add another 2.5lbs and record the volume.
Pressure units: Pounds per square inch, PSI
7. Add 5 pound weight and record the volume.
Pounds (lb) / square inches (in2)
8. Remove the weights.
Pressure in the lab: 14.3
Area of syringe plunger head: 0.75 in2
Charles Law Experiment
1. Utilize a 328 mL flask that has been cooling in a
Charles Law (ex: hot air balloon)
beaker of ice water.
V= k x T
2. Remove the flask and tighten to the stand.
Volume and temperature is directly related.
3. Attach a syringe and thermometer to the stopper on

the flask.
4. Record the initial temperature and volume.
5. Turn on the hair dryer to warm up the flask.
6. At every 5 degree increase, record temperate and
volume of syringe.
Data/Results/Calculations
Boyle's Law:
P= k/V
P1V1= P2V2
-Pressure and volume is inversely related (curve).
-1/P and V are directly related (straight line).
*k is a constant.
