Boyle’s Law
Worksheet 1 SHOW ALL WORK TO RECEIVE CREDIT
Formula for Boyle’s Law: P1V1 = P2V2
Where P1 is initial pressure and P2 is final pressure. Units are: atm, kPa, mmHg, torr
V1 is initial volume and V2 is final volume. Units are L or mL
The formula can be manipulated in the following way:
Initial pressure: P1 = P2 x V2 Initial volume: V1 = P2 x V2
V1 P1
Final pressure: P2 = P1 x V1 Final volume: V2 = P1 x V1
V2 P2
1. The initial volume of a gas is 300.0 mL and has a pressure of 99.0 kPa . If the final pressure is increased to 188 kPa, what will be the final volume in mL?
2. The initial pressure of a sample of helium is 0.988 atm. The initial volume is 1.00 L. What is the final pressure in atm if the sample is placed in a 2.00 L container?
3. Air trapped in a cylinder fitted with a piston occupies an initial volume of 145.7 mL at an initial pressure of 1.08 atm. What is the new volume of air when the pressure is increased to 1.43 atm by applying force to the piston?
4. The initial volume of gas is 0.05 L. At a final pressure of 0.98atm, the final volume is 4.00L. What is the initial pressure of the gas?
