1) A 85cm3 block of iron is removed from an 800oC furnace and immediately dropped into 200 mL of 20oC water. What fraction of the water boils away?
2) The burner on an electric stove has a power output of 2.0kW. A 760g stainless steel tea kettle is filled with 20?C water and placed on the already hot burner.
If it takes 2.30 min for the water to reach a boil, what volume of water, in cm3, was in the kettle? Stainless steel is mostly iron, so you can assume its specific heat is that of iron.
