A gas of mass 1.5kg undergoes a quasi-static expansion which follows a relationship p=a+bV where a and b are constants. The initial and final pressure are 103kPa and 200kPa and corresponding volumes are 0.2m3 and 1.2m3. The specific internal energy of the gas is given by U=1.5pV−85kJ∕kg (where P is in kPa and V in m3∕kg ):

Work done by gas during process is 600kJ
Change in internal energy of the gas is 90kJ
Maximum internal energy during process is approximately 500kJ
Maximum internal energy during process is approximately 300kJ
