In the piston-cylinder system shown in the figure, in the first state, the piston is located on the stoppers and the volume below it is 0.15 m3. There is 2 kg of water at a temperature of 40 oC in the cylinder. The cross-sectional area of the piston is 0.075 m2 and its mass is 35 kg. Atmospheric pressure is 100 kPa and gravitational acceleration is 9.76 m/s2. Then, heat is given to the water until it becomes dry saturated water vapor. Calculate the temperature of the water when the piston starts to move over the stoppers and the work done during the whole process.
