Question: 7 a gas is contained in a vertical frictionless pistoncylinder...

Question details



7. A gas is contained in a vertical, frictionless piston-cylinder device. The piston has a mass 2 of 4 kg and a cross-sectional area of 35 cm A compressed spring above the piston exerts 60 N /atm 95 kPa mp = 4 kg a force of 60 N on the piston. If the atmospheric pressure is 95 kPa, determine the i - pressure inside the cylinder. A = 35 crn2
