(ii) A piston travels between two stops and is restrained by a linear spring as shown. The cross-sectional area of the piston is 0.05 m² and the initial volume of the gas in the cylinder is 0.01 m³. At the top stops, the volume is 0.03 m³. The spring constant is 30.0 kN/m. The gas inside the cylinder is initially at 0.50 MPa and the pressure required to just raise the piston from the stops is 1.00 MPa. The final gas pressure in the cylinder is 2.00 MPa. a) Draw a P-V diagram showing the process. b) Calculate the work done by the gas, in kJ. NNNNN H
