a) Determine the total amount of work done during the process.
b) Calculate the total amount of heat added during this process, clearly stating whether heat is entering or leaving the system.
A piston cylinder device with a linear spring contains 200 g of CO2. Initially the piston is against the stops and the CO2 is contained in a volume of 0.25 m3 at 50 kPa (State 1). The system is then heated until it is at 100 kPa; where the piston just lifts off the stops and begins contacting the linear spring (State 2). More heat is then added until the carbon dioxide reaches 125 kPa and a volume of 0.4 m3 (State 3). Assume the piston is frictionless.
