The data table below shows that as the pressure of a gas sample was changed, the volume of the gas changed. The pressure was measured in atmospheres (atm) and the volume was measured in milliliters (mL).
According to the data table, as the pressure of the gas increases, the volume of the gas:
decreases
increases
remains the same
