A 600-G Piece of Iron at 100°C Is Dropped into a Calorimeter

question 47

Essay

A 600-g piece of iron at 100°C is dropped into a calorimeter of negligible heat capacity containing 100 g of ice at 0°C and 120 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) and the latent heat of fusion of water is
33.5 × 10⁴ J/kg.
