In an experiment with the apparatus shown, the plunger is used to compress helium gas to different volumes. The corresponding volume and pressures (arbitrary units) are measured and displayed in the table below. Which statement best characterizes the data in the table above?

• The volume and pressure values are randomly related

• As the pressure increases, the volume also increases.

• As the volume decreases, the pressure increases.
