Please solve fast and correct this is urgent for me
A piston-cylinder device initially contains 0.82 m3 of air at 212 kPa and 78.2oC. The air is now compressed to 0.47 m3 in such a way that the temperature inside the cylinder remains constant. Determine the work done during this process AW , the pressure P and density A at the terminal process state. Take for air: Rg=287.0 J/(kg K), Cp=1005 J/(kg K), Cv= 718 J/(kg K), k=1.4.
