Water is placed in a piston-cylinder device at 20°c, 0.1 mpa. weights are placed on the piston to maintain a constant force on the water as it is heated to 400 °c. how much work does the water do on the piston, per unit mass? sketch the p-v diagram. (this question requires access to thermodynamic tables). (w = 310.2 kj /kg]
