An unknown composition of gas has undergone a compression process in a piston-cylinder assembly. The relation between pressure and volume for the process is given by pV=constant. The volumes before and after the compression process are 0.1 and 0.045 m, respectively. The final pressure after compression is 2084 kPa. Determine the initial pressure in kPa and the work for the process in kJ if the process is modeled as (a) Isobaric (b) Isothermal and (c) Polytropic (n=1.31)
