Apiston–cylinder device initially contains steam at 3.5 mpa, superheated by 5°c. now, steam loses heat to the surroundings and the piston moves down, hitting a set of stops, at which point the cylinder contains saturated liquid water. the cooling continues until the cylinder contains water at 200°c. determine (a) the initial temperature, (b) the enthalpy change per unit mass of the steam by the time the piston first hits the stops, and (c) the final pressure and the quality (if mixture).
