Name: Ronald Lampkins Date Performed: October 8, 2004 Instructor: Mr. Lee Date Submitted: October 15, 2004 Partner: Jennifer Charlton THE PROPERTIES OF GASES Objective: To study the dependence of the volume of a gas on temperature and pressure. Experimental Data: Charles’ Law Temperature ( C) Length of Trapped Air (cm) Volume of Trapped Air (cm 3) 12.5 6.2 .049 25.0 6.3 .049 35.0 6.4 .050 50.0 6.6 .052 65.0 7.1 .056 75.0 7.2 .057 95.0 7.8 .061 Sample Calculation: Volume of Trapped Air = Pi*radius 2 *Length of trapped air Pi(.05 2 )*6.2 cm = .049 cm 3 Boyle’s Law Volume of Air in Syringe (mL) Pressure (torr) Pressure of Air in Syringe (torr) PV Product (mL*torr) 0 964.8 1724.8 0.0 3 129.2 889.2 387.6 5 -93.3 667.7 -466.5 6 -170.4 589.6 -1022.4 7 -228.3 531.7 -1598.1 9 -336.7 423.3 -3030.1 10 -362.2 397.8 -3622.0 11 -392.0 368.0 -4312.0 12 -414.0 346.0 -4968 13 -438.4 321.6 -5699.2 14 -453.2 306.8 -6344.8 16 -487.7 272.3 -7803.2 18 -511.2 248.8 -9201.6 20 -513.2 246.8 -10264.0 Sample Calculation: Pressure of air in syringe = pressure (torr) + 760 torr 760 torr + 964.8 torr = 1724.8 torr PV product = volume of air in syringe * pressure
