Verification of Boyle's law

Label This Diagram

Method • 1

• Pump air into reservoir until oil compresses the air in the tube

• Disconnect pump

Method • 2

• Read volume of air from the scale

• Read pressure of air from the pressure guage

Method • 3

• Reduce pressure by opening valve screw

• Read new volume and pressure values

Method • 4

• Repeat previous steps until pressure is back to normal

• Calculate 1/V for each value of V

Method • 5

• Plot graph

• Graph shows that p is proportional to 1/V

Precautions • 1

Read pressure and volume scales at eye level to avoid parallax error

Precautions • 2

Wait for gas to return to room temperature after each pressure adjustment

Name the labels used to graph this experiment

• x - 1/V - cm-3

• y - P - Pa
