Africtionless piston-cylinder with stops has an initial volume of 1.2 m^3 and contains 2.4 kg of water with an initial temperature of 100°c. at this state, the piston is partially supported by a set of stops. the mass of the piston is such that a pressure of 300 kpa is required to lift the piston off of the stops. the system is heated until the temperature is 250°c. a. determine the initial pressure of the water b. if the piston lifts off the stops during the process, find the temperature when the piston first begins to rise. if the piston doesn't lift off the stops, determine the final pressure. c. calculate the work for the process. d. calculate the heat transfer for the process. e. show the entire process on p-v and t-v diagrams.
