Fortunately, because quantum dots are packed
together at high densities — more than 50 billion dots per square centimeter — they capture electrons and holes before the particles are lost.
So it's all gases
at greatest
density will be doing the same thing around the planet
at the same time (*) and as these change with differences in
density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the
higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in
density and kinetic energy as a sort of band of brothers near the surface will rise and cool
at the same time whereupon they'll all come down
together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.
