Water is being heated in a closed pan on top of a range while being stirred by a paddle wheel. During the process, 40 kJ of heat is added to the water and 5 kJ of heat is lost to the surrounding air. The paddle-wheel work amounts to 2 kJ. In the question that follows, select the answer that is closest to the true value. What is the change in internal energy of the water in units of kJ ?
