The 4cm thick large copper plate, initially at a uniform temperature of 25oC, is heated by passing it through an oven kept at 400oC. The copper plate remains in the oven for 5 minutes. Calculate the surface temperature of the copper plate when it is taken out of the furnace by taking the heat transfer coefficient h = 200W / m2oC. Properties of copper at room temperature:
