Rebekah set up a different experiment as shown below.
She measured the volume of the liquid and the air in the
cylinders before and after a 200 g load was added to the piston.
When the loads were added to the pistons, the volume of the liquid did not change but the volume of the air decreased.
Explain why this happened
