Oxygen (O2) gas within a piston-cylinder assembly undergoes an expansion from a volume V1 = 0.01 m^3 to a volume V2 = 0.03 m^3. The relationship between pressure and volume during the process is p = AV^-1 + B, where A = 0.06 bar * m^3 and B = 3.0 bar. For the O2, determine (a) the initial and final pressures, each in bar, and (b) the work, in kJ.
