1) A 85cm³block of iron is removed from an 800^oC furnace and immediately dropped into 200 mL of 20^oC 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.
