Oxygen (O2) gas within a piston-cylinder assembly undergoes an expansion from a volume V1= 0.01 m3 to volume V2 = 0.03 m3. The relationship between pressure and volume during the process is p=AV-1+B, where A= 0.06 bar.m3 and B= 3.0 bar. For the O2, determine
(a) The initial and final pressure, each in bar, and
(b) The work, in kJ.
