Content Substance Latent Heat (J/kg) 2,260,000 Steam water Ice water 333,000 Answer the following questions dealing with methods of heat transfer. Radiation An orange orb has an emissivity of 0.113 and its surroundings are at 183°C. The orange orb is absorbing heat via radiation at a rate of 966 W and it is emitting heat via radiation at a rate of 591 W. Determine the surface area of the orb, the temperature of the orb, & Pet A= Torb= Poal = Convection The exterior walls of a house have a total area of 206 m² and are at 11.4°C and the surrounding air Is at 6.6° C. Find the rate of convective cooling of the walls, assuming a convection coefficient of 3.1 W/(m².C). Since you're looking for the rate of cooling, your answer should be entered positive. Conduction Ice of mass 12.3 kg at 0°C is placed in an ice chest. The ice chest has 3 cm thick walls of thermal conductivity 0.04 W/m-K and a surface area of 1.33 m². Express your answers with appropriate mks units. (a) How much heat must be absorbed by the ice during the melting process? (b) If the outer surface of the ice chest is at 28° C, how long will it take for the ice to melt?
