1. 1. BOYLE’S LAW
2. 2. ROBERT BOYLE Robert Boyle was natural philosopher,chemist,physicist and inventor.He is famous for “Boyles Law” .
3. 3. INTRODUCTION •In 1662 robert studied the relationship between the volume and pressure of a gas at constant temperature
4. 4. DEFINITION • The product of Pressure and volume of a fixed mass of a gas is constant at a constant temperature. • FORMULA:- • Volume < 1 𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 V= 𝐾 𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 or VP =K
5. 5. Here “k” is proportionality constant the value of “k” is same for the same amount of given gas P1V1 = K Then P2V2=K WHERE;- P1= Initial pressure P2 = final pressure V1= Initial Volume V2 =final volume
6. 6. EPERIMENTATION VERIFICATION OFBOYLE’S LAW  Let us take some mass of a gas in cylinder having a moveable piston and observe the effect of increase of pressure on it’s volumewhen the pressure of 2atm pressure is applied.the volume of gas reads a 1dm3.when pressure is increased to 4atm. The volume of gas reducse to 0.5 dm3.when we increased it at three times on 6atm it will be 0.33dm3 . And when we increase it into 8atm its volume will be 0.25dm 3
7. 7. When a calculate the product of volume and pressure for this experiment. The product of all these experiment is constant at 2atm dm3.It proves the “Boyle’s law”
