A 200-Kg Block of Ice at 0

Multiple Choice

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.
