A cylinder with a piston contains 0.150 mol of nitrogen at 1.80 X105 Pa and 300 K. The nitrogen may be treated as an ideal gas. The gas is first compressed isobarically to half its original volume. It then expands adiabatically back to its original volume, and finally it is heated isochorically to its original pressure.
(a) Show the series of processes in a pV-diagram.
(b) Compute the temperatures at the beginning and end of the adiabatic expansion.
(c) Compute the minimum pressure.
