2 As the pressure on a gas increases As the pressure on a gas ____________ - the volume ___________ Pressure and volume are _________ related 1 atm 4 Liters 2 atm 2 Liters

3 As the ___________on a gas increases - the ________ decreases __________ and _________ are inversely related 2 atm 2 Liters

4 Boyle’s Law Timberlake, Chemistry 7 th Edition, page 253

5 Boyle's Law If n and T are constant, then PV = (nRT) = k This means, for example, that __________ goes up as _________ goes down. Robert Boyle (1627 - 1691) Son of Early of Cork, Ireland. A bicycle pump is a good example of Boyle's law. As the volume of the air trapped in the pump is reduced, its pressure goes up, and air is forced into the tire.

12 Air Pressure Water pressure increases due to greater fluid above opening.

13 Pressure and Volume of a Gas Boyle’s Law A quantity of gas under a pressure of 106.6 kPa has a volume of 380 cm 3. What is the volume of the gas at standard pressure, if the temperature is held constant?

14 PV Calculation (Boyle’s Law) A quantity of gas has a volume of 120 cm 3 when confined under a pressure of 93.3 kPa at a temperature of 20 o C. At what pressure will the volume of the gas be 30 cm 3 at 20 o C?
