Metal balls 10 mm in diameter are to be annealed by heating


Metal balls 10 mm in diameter are to be annealed by heating them to 827°C then allowing them to cool slowly in air at 27°C to the point where they are in thermal equilibrium with the air. 2000 balls are annealed in one hour’s time. What is the total rate of their heat transfer if they are made of carbon steel, stainless steel, or copper?
