A human with a surface area of 2 m^2 and a surface temperature of 27 degrees celcius radiates into a large room (which acts as a black body), the surfaces of which are at 15 degrees celcius. The human is covered with brightly colored apparel that has a surface emissivity of 0.25. Determine the rate of heat exchange between the human and the room.
