A piston–cylinder device initially contains 0.6 m3 of saturated water vapor at 250 kPa. At this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 300 kPa is required to move it. Heat is now slowly transferred to the steam until the volume becomes 1.5 m3. Use the data from the steam tables. a) Determine the final temperature. b) Determine the work done during this process. c)...

Consider a piston-cylinder device (system) that contains 0.06 m3 of air at 300 kPa and 125 ̊C. (a) If the volume of air in the device increases to 0.15 m3 while the pressure remains constant, determine the work done by the system during the process. (b) If as a result of heat transfer to the surrounding, the pressure and temperature in the device drop to 240 kPa and 55 ̊C, respectively, and the piston is held such that the volume...

Problem 1 A piston-cylinder system contains a paddle stirrer (a paddle with blades that can stir the contents of the cylinder). The cylinder contains a gas that is initially at 150 kPa and occupies a volume of 0.196 m3 . The piston is unrestrained and has a cross-sectional area of 0.196 m2 . 20 kJ of electrical energy is supplied to the paddle stirrer, resulting in the piston moving up by 0.2 m. During this process, 5.27 kJ of heat...
