The adjoining figure illustrates a piston-cylinder arrangement. This cylinder contains helium at 21oC and 1.379 MPa. The gas is compressed suddenly from 98 to 82 cm3 because of the The Pennsylvania State University Page 1 of 2 https://en.wikipedia.org/wiki/Space_Shuttle piston's weight, with the final temperature reaching 27oC. (Molecular weight of helium = 4 gm/mol; Ru = 8.314 J/mol-K) A) Determine the final pressure. (8) B) Was the compression undergone by the gas a quasi-equilibrium process? Provide a viable reasoning behind your answer. (2) C) The piston of this cylinder has a cross-sectional area of 0.029 m2. Atmospheric pressure is 0.1035MPa and the acceleration due to gravity is 30.1 ft/s2. The system is in static mechanical equilibrium after the gas is compressed to 82 cm3. What is the mass (kg) of the piston?
