A vertical, frictionless piston-cylinder device contains a gas at 600 kPa absolute. The atmospheric pressure outside is 100 kPa absolute. The piston has a diameter of 50 mm. a) Determine the mass of the piston. b) If the mass of the piston is now halved---- what would be the gauge pressure of the gas?
