Five kilograms of a two-phase liquid-vapor mixture of water initially at 300°C and x1 = 0.8 is heated from the initial state to a saturated vapor state while the volume remains constant. The process is brought about by heat transfer from a thermal reservoir at 380°C. The temperature of the water at the location where the heat transfer occurs is 380°C. Let To = 300 K, po = 1 bar, and ignore the effects of motion and gravity. Determine the net amount of exergy transfer by heat, in kJ.
