The burner on an electric stove has a power output of 2.0 kW. A 810g stainless steel tea kettle is filled with 20 C water and placed on the already hot burner. If it takes 2.90 min for the water to reach a boil, what volume of water, in cm^3, was in the kettle? Stainless steel is mostly iron, so you can assume its specific heat is that of iron.
