termo2

2) A gas is compressed from an initial volume of 0.42m3 to a final volume of 0.12m3. During the quasi-equilibrium process, the pressure changes with volume according to the relation P= aV+b, where a=21200kPa/m3 and b=600kPa. Calculate the work done during this process (a) by plotting the process on a PV diagram and finding the area under the process curve and (b) by performing the necessary integrations
