A sample of a gas in a cylindrical chamber with a movable piston occupied a volume of 2.86 cubic meters when the pressure was 9.85 × 104 Pa and the temperature was 25.8 ºC. The pressure was readjusted to 1.08 × 105 Pa by moving the piston. What was the volume occupied by the sample under the new conditions if the temperature remained constant throughout?
