A coin of diameter 2.5 cm is placed concentrically at the bottom of a can 5 cm in diameter and 10 cm high. The coin is heated to 500 K while the cylindrical surface of the can is maintained at 330 K. The top of the can is opened to a surroundings at 300 K. Determine the heat transfer from the coin to the cylindrical surface and to the surroundings. Assume blackbody radiation.
