Question: A piston - cylinder device initially contains 4 . 8 - kg saturated liquid water at 3 0 0 C . Now heat is transferred

A piston-cylinder device initially contains 4.8-kg saturated liquid water at 300C. Now heat is transferred to the water until the final volume reaches 5 times of the initial volume and all the liquid turned into vapor. Determine the enthalpy change of the water. Write your answer in kJ with 2 decimal figures.
