Let the pestant set of cylinders illustrated in the following figure where the piston without friction is free to move between 2 sets started the volume delimited by the piston in contact with the lower stops and of 400 l and they is 600 l when the piston reaches the higher budgets initially the cylinder is filled with water at 100 kilopascal at a title of 20% the system is heated until the water becomes saturated steam if the mass of the piston and such that a pressure of 300 kilopascal Is needed to lift it against ambient pressure calculate the final pressure gives the cylinder the amount of heat exchanged and the work done during the entire evolution
