A 100-g chunk of 72 ∘C iron is dropped into a cavity in a very large block of ice at 0∘C.

Question

What is the mass of ice that melts. (The specific heat capacity of iron is 0.11 cal/g⋅∘C.).

Answer 1

heat of fusion for ice ... 79.7 cal/g

heat from iron
... 100 g * 72 ºC * 0.11 cal/g⋅ºC

divide heat from iron by heat of fusion

Answer 2
