2-37 Water is being heated in a closed pan on top of a range while being stirred by a paddle wheel. During the process, 30 kJ of heat is transferred to the water, and 5 kJ of heat is lost to the surrounding air. The paddle-wheel work amounts to 500 Nm. Determine the final energy of the sys- tem if its initial energy is 10 kJ. Answer 35.5 kJ ,5 kJ 500 N-m 30 kJ
