As shown below, an insulated iron wire is immersed in 884 g of water at 24 °C. The wire is 4.1 cm long and has a cross-sectional area of 0.001 cm?. A.) Determine how much heat is needed to bring the water to a boil. The specific heat of water is 4186 J/kg-K. Q = B.) Determine how long it will take to bring the water to a boil if a 29 A current is run through the wire. Assume all the thermal energy generated by the wire is absorbed by the water.
