A closed system containing 2-kg of air undergoes an isothermal process from 600-kPa and 200°C to 80-kPa. Determine:
1.1) The initial volume of the system.
1.2)The work done during the process. Give your answer in kJ.
1.3) The heat transfer during the process. Perform an energy balance from which you will derive the equation to calculate the heat transfer. Give your answer in kJ.
1) V1 = 0.4525 m3
2) W = 547.0522 Kj
3) Q = 547.0522 Kj
