4- 3kg of acetone with 60% quality is heated in a cylinder with a piston at constant pressure until all the acetone vaporizes. The temperature at the final state is 400K. Applying the PengRobinson equation of state and the vapor pressure equation for acetone, calculate the work done. lnPvap=10.0311T35.932940.46 ( Pvap is in bar and T is in K ) 4- 3kg of acetone with 60% quality is heated in a cylinder with a piston at constant pressure until all the acetone vaporizes.
