1. A frictionless device consisting of a cylinder-piston contains 16 lbm of superheated water vapor at 40 psi and 600F. The steam cools at constant pressure until 70% of the mass is condensed. determine the work done during this process
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 relationship P=aV+b, where a=1200kPa/m3 and b=600kPa. Calculate the work done during this process: a) Graphing the process on a P-V diagram and determining the area under the process curve. b) Carrying out the necessary integrations
