1.25 kg of a gas within a piston-cylinder assembly, undergoes an expansion from a volume of v1=0.1m3 to a volume of v2=0.3m3, through a polytropic process with n=1.25. It then undergoes a second expansion to a volume of v3=0.5m3, through a process where p=((0.05bar*m3)/v)+2bar. The changes in specific internal energy for the two expansions are u2-u1=-50kJ/kg, and u3-u2=-15kJ/kg. Find p1,p2,p3(in bar), work of the fluid from 1 to 2(in kJ), and the net heat transfer from 1 to 2(in kJ).
