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 ( ) 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.

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