Water is being cooledd in a closed container while being stirred by a paddle wheel. During this process, 25 kJ of heat is taken away from the water, and 15 kJ of heat is added to the water. The paddle-wheel work amounts to 5 N.m. Determine the final energy of the system if its initial energy is 10 kJ. (Sketch the system boundaries)
