JZUKAN-144 To determine the relative amount of heat absorbed by each bowl when placed in the same surroundings, we need to consider the concept of emissivity. Emissivity is a measure of an object’s ability to absorb and emit thermal radiation. It ranges from 0 to 1, with 1 being a perfect absorber and 0 being a perfect reflector. Given that one bowl is black and the other is shiny, we can conclude that these bowls will have different emissivities. The black bowl has a high emissivity (close to 1) as it absorbs nearly all incoming infrared radiation. On the other hand, the shiny bowl has a low emissivity (close to 0) as it reflects most of the incoming infrared radiation. Since the black bowl absorbs more thermal energy, it will stay hotter longer compared to the shiny bowl. Consequently, the shiny bowl will lose heat faster in the same surroundings. Therefore, the shiny bowl will lose the most heat. The correct answer is 0.
