3. (20 pts) A piston-cylinder device initially contains 50 L of liquid water at 40C and 200 kPa. Heat is transferred to the water at constant pressure until the entire H2O liquid is vaporized. 40C 200 kPa (a) What is the mass of the liquid water? (b) What is the final temperature? (C) Determine the total enthalpy change.(choices: a. 15,450 KJ b. 2750 kJ C. 165 kJ d. 125,950 kJ) (d) Show the process on a T-v diagram with respect to saturation lines
