5. (30 Points) the volume of 1 kg of Helium in a piston-cylinder device is initially at 5 m3. Now helium is compressed to 2 m3 while its pressure is maintained constant at 180 kPa. Assuming ideal gas behavior of Helium, determine (a) temperature, in K, at state 1. (b) temperature, in K, at state 2. (c) work, in kJ (d) heat transfer, in kJ. Take the molecular weight (M) of Helium to be 4.003 kg/kmol and cp=5.1926 kJ/kgK
