This relationship is shown by Boyle’s law. First, open the side arm and record as 1 atm. Third, close the side arm and pull the plunger to 10 mL and record this as 0.5 atm. Collect data for 5 mL, 7.5 mL, 10 mL, 12.5 mL, 15 mL, 17.5 mL, and 20 mL. Print a copy of the graph window and data window. volume (mL) Pressure(atm) Constant, k (PxV) When the volume was doubled from 5.0 mL to 10.0 mL the pressure was halved from 2.0 atm to 1.0 atm. If the volume is halved from 20.0 mL to 10.0 mL the pressure is doubled from 0.5 atm to 1.0 atm. If the volume is tripled from 5.0 mL to15.0 mL the pressure is multiplied by 1/3. It went from 2.0 atm to 0.7 atm. The relationship between the pressure and volume of a confined gas is inverse. The line of the graph is curved not straight, this indicates an indirect relationship. If the volume was 40 mL. the pressure would be 0.25 atm. 40 x 0.25 =10.0. If the volume was 2.5 mL the pressure would be 4.0 atm. 2.5 x 4.0 = 10.0. The number of moles of the gas and the temperature are assumed to be constant in this experiment. PV=k. Pressure is inversely proportional to volume. Pressure is directly proportional to the reciprocal of volume. This can be proved mathematically. Bibliography: Word Count: 318
