surface temperature

1. The black grille on the back of a refrigerator has a surface temperature of 35â—¦C with a total surface area of 1 m2. Heat transfer to the room air at 20â—¦C takes place with an average convective heat transfer coefficient of 15 W/m2 K. How much energy can be removed during 15 minutes of operation?

2. A steel pot, with conductivity of 50 W/m K and a 5-mm-thick bottom, is filled with 15â—¦C liquid water. The pot has a diameter of 20 cm and is now placed on an electric stove that delivers 500 W as heat transfer. Find the temperature on the outer pot bottom surface, assuming the inner surface is at 15â—¦C.
