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) This is more usually written as: Pressure = constant volume PV= k P 1 V 1 =P 2 V 2

? 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 We can calculate the pressure by dividing the
