Metal plates (k = 180 W/m·K, ρ = 2800 kg/m3, and cp = 880 J/kg K) with a thickness of 1 cm are being heated in an oven for 2 min. Air in the oven is maintained at 800°C with a convection heat transfer coefficient of 200 W/m2·K. If the initial temperature of the plates is 20°C, determine the temperature of the plates when they are removed from the oven.
