Boyle's law
Leaving Cert Chemistry · Behaviour of Matter
Higher Level
At constant temperature the volume of a fixed mass of gas is inversely proportional to the pressure applied to it. Doubling the pressure therefore halves the volume, and a graph of pressure against 1/volume gives a straight line through the origin.
Ordinary Level
At a steady temperature, squashing a fixed amount of gas into a smaller volume raises its pressure. Pressure and volume are inversely proportional.
