Behavior of Gases
Experiment 4: Behavior of Gases
Introduction:
In this experiment, the problem trying to be solved is what gas laws are being used when the pressure, temperature, and volume are being measured. The three gas laws are Boyle’s Law, Charle’s Law, and Gay-Lussac’s Law. The Boyle’s Law is when volume and pressure are being compared. Pressure and volume are inversely proportional, because when pressure goes up, volume goes down. The Charle’s Law is when volume and temperature are compared. Volume and temperature are also inversely proportional as well. Lastly, Gay-Lussac’s Law is when pressure and temperature are compared. Pressure and temperature are directly proportional; therefore when pressure goes up, temperature also goes up. The formulas are as follows:
Boyle’s Law: P2 P1 = P2 V2
Charle’s Law: V1/T1 = V2/T2
Gay-Lussac’s Law: P1/T1 = P2/T2 Hypothesis: If volume, temperature, and pressure are measured, they will follow the laws and fit under Boyle’s, Charle’s, or Gay-Lussac’s law. Expected Results: It should be expected that when volume and pressure are measured, pressure will go up and volume will go down. When volume and temperature are compared, volume will go up and temperature will go down. Lastly, when pressure and temperature are measured, pressure will go up as temperature goes up.
