Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (Ļ = 2770 kg/m3 and cp = 875 j/kgĀ°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22Ā°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200Ā°c.
