this question is already on chegg but i still need the bolded part. the overall change in internal energy is supposed to be 1301.4 kJ/kg

10. 3-44) Water initially at 200 kPa and 300C is contained in a piston-cylinder device fitted with stops. The water is allowed to cool at constant pressure until it exists as a saturated vapor and the piston rests on the stops. Then the water continues to cool until the pressure is 100 kPa. On the T-v diagram, sketch, with respect to the saturation lines, the process curves passing through the initial, intermediate, and final states of the water. Label the T, P, and y values for end states on the process curves. Find the overall change in internal energy between the initial and final states per unit mass of water. Determine the total heat transfer during the process? Hint: consider work during process 1-2 and then apply energy conservation. e Water 200 kPa 300C FIGURE P3-44
