    A 2kg block of ice at 0 degrees celsius is dropped into a very large lake at 25 degrees celsius and completely melts. For water, the heat of fusion is 3.35*10^5 J/kg, the heat of vaporization is 2.25*10^5 J/kg, and the specific heat is 4190 J/kg*K. What is the net change in entropy of the system consisting of cie and the lake due to this melting process?
