A blacksmith cools a chunk of iron initially at 625 °C by trickling water from a jug over it. The water in the jug has a temperature of 20.0°C. All of the water boils away and the iron chunk cools down 120 °C. If, in total, he poured 0.80 kg of water over the iron, what is the mass of this chunk of iron?
The specific heat capacity for water is 4190 J/(kg.°C). Water has a melting point of 0°C and a boiling point is 100°C. The latent heat of fusion for water is 3.34 x105 J/kg and its latent heat of vaporization is 2.26 x106 J/kg.
The specific heat capacity for iron is 470 J/(kg.°C). Iron has a melting point of 1538°C. The latent heat of fusion for iron is 2.47 x105 J/kg
