178. 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 N-m. Determine the final energy of

the system if its initial energy is 10 kJ.

A. 35.5 kJ B. 40.5 kJ

C. 25.5 kJ D. 14.5 kJ
