1. (3 Points) Air in a piston cylinder at 220 kPa, 323 C is expanded in a constant pressure process to twice the initial volume (state 2). The piston is then locked with a pin and heat is transferred until a final temperature of 823 K is reached (state 3). Assume ideal gas behavior and constant specific heat values for air. a) Sketch the process in P-v and T-v coordinates. b) Find P (in kPa) and T (in C) at states 2 and 3. c) Find the work and heat transfer for both processes (process 1 to 2 and process 2 to 3) in kJ/kg. d) Calculate the change in entropy for air in both the processes e) Assuming T, is 300K comment on the reversibility/irreversibility/possibility of the process.
