Two kilograms of an ideal gas with constant cp=1kJ/kgK and cv= 0.7kJ/kgK are contained in an insulated piston-cylinder device with an initial volume of 0.3m3 and a pressure of 10bar. The piston is then allowed to move until the volume quadruples.
If the process is considered reversible, determine:
a) The temperature of the final state in K.
b) The work in kJ.
If irreversibilities during the process cause the entropy to increase by 0.1kJ/K, determine:
c) The temperature of the final state in K.
d) The work in kJ.
e) Sketch the reversible and irreversible processes in a T-s diagram.
