A sample of a gas in a cylindrical chamber with a movable piston occupied a volume of 8.50 liters when the pressure was 9.85 × 10⁴ Pa and the temperature was 24.9°C. The volume of the system was readjusted to 11.6 liters by moving the piston. What is the pressure exerted on the surface of the piston by the gas if the temperature of the system remained constant?

Using Boyle's Law (P1V1 = P2V2), where the temperature is constant, the new pressure P2 can be calculated as (9.85 × 10^4 Pa * 8.50 L) / 11.6 L = 7.22 × 10^4 Pa.
