An 920-g piece of iron at 100°C is dropped into a calorimeter of negligible specific heat containing 50 g of ice at 0°C and 92 g of water, also at 0°C. What is the final temperature of the system? The specific heat of iron is 448 J/kg ∙ K, that of water is 4186 J/kg ∙ K, and the latent heat of fusion of water is 33.5 × 104 J/kg.
A) 0°C
B) 11°C
C) 14°C
D) 24°C
E) 32°C
