A 2.00-kg block of ice at 0.00°C is dropped into a very large lake at 25.0°C and completely melts. For water, the heat of fusion is 3.35 × 105 J/kg, the heat of vaporization is 2.25 × 105 J/kg, and the specific heat is 4190 J/kg•K
The net change in entropy of the system consisting of the ice and the lake due to this melting process is closest to A) 2.45 × 103 J/K. B) 2.24 × 103 J/K. C) 2.06 × 102 J/K. D) -2.45 × 103 J/K. E) -2.06 × 102 J/K.
