An electronic package with a surface area of 1 m² placed in an orbiting space station is exposed to space. The electronics in this package dissipate all 1 kW of its power to the space through its exposed surface. The exposed surface has an emissivity of 1.0 and an absorptivity of 0.25. Determine the steady state exposed surface temperature of the electronic package

(a) If the surface is exposed to a solar flux of 750 W/m²,

(b) If the surface is not exposed to the sun.
