A piston-cylinder device initially contains 50 L of liquid water at 40'C and 200 kPa. Heat is transferred to the water at constant pressure until the final temperature is 125*C. Determine: (a) What is the mass of the water? (10 pts.) (b) What is the final volume? (15 pts.) (c) Determine the total enthalpy change. (15 pts.) (d) Show the process on a T-v diagram with respect to saturation lines. (10 pts.)
