What temperature will the top of the hood reach

Reference no: EM13315511

Assume the steel in the body of an automobile has an emissivity of 0.3 and a specific heat of 450 J/Kg-degree C. Take the area of the hood of the automobile directly exposed to the sun as 3.5 square meters, and its mass as 24.0 kg. What temperature will the top of the hood reach, assuming it lost heat by radiating to its surrounding environment, which is at 20 degrees C?
