A cylinder fitted with a frictionless piston contains R-134a at 40oC, 80% quality, at which point the volume is 10 L. The external force on the piston is now varied in such a manner that the R-134a slowly expands in a polytropic process to 400 kPa, 20oC. Calculate the work and the heat transfer for this process.
