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. _________________________________________________...
