P (Pa) 6x106 4 x 106 2x106 -- -v (ms) (a) Determine the work done on a gas that expands from i to fas indicated in the figure. The work done by the gas will be positive when it expands. The problem asks for the work done on the gas (b) How much work is performed on the gas if it is compressed from fto i along the same path? You appear to have given the correct answer using your incorrect result from part (a). MJ Need Help?

a)
Workdone by the gas = Area under P-V curve
= 0.25*6*10^6 + 0.25*2*10^6 + 0.5*0.25*(6-2)*10^6 + 0.25*2*10^6
= 3*10^6 J
workdone on the gas = -3*10^6 J
= -3 MJ <<<<<<<-----------Answer
b) in compression,
work perfomred on the gas = +3 MJ <<<<<<<-----------Answer
