What is Boyle’s Law? Boyle’s Law is one of the laws in physics that concern the behaviour of gases When a gas is under pressure it takes up less space: The higher the pressure, the smaller the volume Boyles Law tells us about the relationship between the volume of a gas and its pressure at a constant temperature The law states that pressure is inversely proportional to the volume
How can we write Boyle’s Law as a formula? Pressure is inversely proportional to the volume and can be written as: Pressure α 1/volume P=pressure in N/m 2 V=volume in dm 3 (litres) k =constant This is more usually written as: Pressure = constant volume PV= k P 1 V 1 =P 2 V 2

How can we investigate Boyle’s Law ? When investigating Boyles law a given volume of gas is sucked into a cylinder and the end is sealed The temperature of the gas is kept constant Using several equal weights we can apply increasing pressure to the gas
