How much energy can be removed during operation

Question

Problem

1. The black grille on the back of a refrigerator has a surface temperature of 35^oC with a total surface area of 1 m². Heat transfer to the room air at 20^oC 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 15^oC 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 15^oC.

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
