A piston-cylinder assembly contains 1kg of water, initially occupying a volume of 0.5m^3 at

 0.1Mpa.

Energy transfer by heat to the water result in an expansion at constant temperature to a final

volume of 1.6941m^3 Kinetic and potential energy effect are negligible.

For the water,(a) show P-vdiagram

                       (b)evaluate the work, in kJ/kg and

                        (c) evaluate the heat transfer, in kJ

제발좀 도와주세요!! ㅠㅠㅠㅠㅠㅠ

아 그리고  표보니까 1.6941 m^3 일때 saturated vapor 상태이더라구요 혹시나 필요한건가..싶어서같이 적어놓아요
