Robert Boyle conducted an experiment on gases to study the deviation of its behaviour in changed physical conditions. It states that under a constant temperature when the pressure on a gas increases its volume decreases. In other words according to Boyle’s law volume is inversely proportional to pressure when the temperature and the number of molecules are constant. K 1 here is a proportionality constant, V is the Volume and p is the pressure. Now, if a fixed mass of gas undergoes an expansion at constant temperature then the final volume and pressure shall be p 2 and V 2. The initial volume and initial pressure here is p 1 and V 1 then according to Boyle’s law: p 1×V 1 = p 2×V 2 = constant (k 1) So according to Boyle’s law, if the pressure is doubled then at constant temperature the volume of that gas is reduced to half. The reason being the intermolecular force between the molecules of the gaseous substance.
