Hydrogen gas (H2) is initially at a pressure of 20 bar and temperature of 300'C (state 1), while occupying a volume of 0.5 m3 in a frictionless piston-cylinder arrangement. The gas then undergoes a reversible cycle in which it expands isothermally to a pressure of 8 bar (state 2). This is then followed by adiabatic compression to restore the pressure back to 20 bar. The cycle is then completed by a constant pressure process. Sketch the process of p-v and...
