A piston cylinder is initially at a state of 60c, 200kpa. Heat is added to the system from 500c reservoir until the final pressure is 400kpa. the mass of the air is 2kg, the spring constant is 1000kn/m and the cross sectional area of the piston is 0.1m^2. the piston moves 0.1 m before contacting the linear spring. The outside temp is 25c and the pressure is 1 bar. a) What is the work done by the air in the cylinder? b) What is the heat transfer? c) What is Sgen d)What is the change in exergy of the air?
