A piston-cylinder arrangement contains Carbon dioxide (CO2) initially at 66 kPa and 400 K, undergoes an expansion process with pressure-volume relationship of PV 1.2 = Costant.to a final temperature of 298 K. Assuming the gas to be an ideal gas, determine the final pressure (kPa), the work done and the heat transfer each in kJ.
CAN YALL PLEASE HELP ME I HAVE 4 HOURS TO DO THESE!! THANK YOU!! Question 1 A mass of 4 kilograms of air in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 0.3 MPa, T1 = 211°C: Process 1–2: Constant-temperature expansion until the volume is twice the initial volume. Process 2–3: Constant-volume heating until the pressure is again 0.3 MPa. Assuming ideal gas behavior, determine the temperature at state 3, in kelvin. _________________________________________________...
