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.
