A piston- cylinder assembly contains 3kg of acetone with 60% quality. The system is heated at constant pressure until all the acetone is vaporized. Assume that acetone is represented by the PR EOS. The vapor pressure of acetone is given by

lnPsat=10.0311T35.932940.46 Where P is in bar and T in K. The critical properties and acentric factor of acetone are Tc=508.0KandPc=48.0bar=0.304 Calculate the work done if the temperature at the final state is 400K
