stion 34 of 65 > A gas is in a sealed container with a moveable piston. The original pressure is 113 kPa and the original volume is 0.170 m. If the piston is moved outward to make the volume 0.540 mº, what will the new pressure be? Assume that the temperature of the gas is kept constant 0.0281 kPa O 35.6 kPa 0.00279 kPa 359 kPa Now, suppose that the original conditions remain the same but the piston is moved...
