Very high in the Earth’s atmosphere, the temperature 4 igsc9n( d3imcan be 700 k+cfjo0d+i 6i.t.u vg$^{\circ} C$ . Yet an animal there would freeze to death rather than roast. Explain.
参考答案:
Even though the temperature is high in the upper
atmosphere, the density of gas particles is very low. There would be relatively very few collisions
of high-temperature gas molecules with the animal to warm it. Instead, the animal would radiate heat to the
rarified atmosphere. The emissivity of
the animal is much greater than that of the rarified atmosphere, and so the
animal will lose much more energy by radiation than it can gain from the
atmosphere.
