IB Physics SL B 3 4 Empirical Gas Laws Questions question 1
The equipment shown in the diagram was used by a student to investigate the variation with volume, of the pressure p of air, at constant temperature. The air was trapped in a tube of constant cross-sectional area above a column of oil.
The pump forces oil to move up the tube decreasing the volume of the trapped air.
Outline how the results of this experiment are consistent with the ideal gas law at constant temperature.
