Water is being heated in a closed vessel on top of a range while being stirred by a paddle wheel. During the process, 300 kJ of heat transferred to the water, and 150 kJ of heat is lost to the surrounding air. The paddle wheel work amounts to 0.25 kJ. If the initial energy of the system is 200 kJ, then the final energy of the system in kJ is
