1. Would a flagpole made of steel or aluminum freeze one's tongue to it faster? Why? (Thermal conductivity)
2. The outer surface of a satellite in space has an emissivity of 0.8 and an absorptivity of 0.3 for solar radiation. If solar radiation is incident on the spacecraft at a rate of 1000 W/m2, determine the surface temperature (K) of the spacecraft when the radiation emitted equals the solar energy absorbed.
