CHEM 103 EXPERIMENT 5 GAS LAWS ALL SOLUTIONS WITH EXPLANATIONS + ADDITIONAL NOTES AS PER MARKING SCHEME 2022/2023 NBPL05: Experiment 5 - Gas Laws Purpose: Experiments on different gas laws Notes: ● Robert Boyle Law - pressure of a gas is inversely related to its volume. K is a constant. ● P1V1=P2V2 Demonstration of Bolye’s Law - looking at pressure and volume. ● A syringe is used and it is fitted onto a wooden base and then capped off with a platform. ● Open to the atmosphere - pounds per inch = 14.3 pounds per square inch. ● Volume that is in the syringe with the atmospheric pressure = 33mL is ● Adding to pressure by 2.5 pound weight. Gas gets compressed by the plunger as it gets pushed down. Now it's 27ml with 2.5 pounds on it. ● Total of 5 pounds now the pressure = 22.5 ml ● 7.5 pounds added = 18ml ● 10 pounds added = 16.5ml ● 15 pounds added = 13.0ml ● The higher the pressure added the lower the volume gets. Jacques Charles Law ● V=K*T ● Volume and how the temperature is related. ● As we increase the volume the temperature is going to increase ( balloon example) ● V1/T1 = V2/T2
