Thanks, I’ll have a look. It’s an universal mains power supply with no voltage switch.

you’d almost certainly notice the change in gravity.

Really? can you actually percieve the sun gravity? Do you mean that we would get like a tsunami beause of the tidal effect? Now I kinda want a documentary about this.

Yeah “dissipate away” is probably a bit misleading but I meant that the heat source is mainly the surface since it’s difficult to heat the thin outer layers directly, and from there heat moves up thorough ir radiation or adiabatic expansion. But it’s not like mountains are cooled down by adiabatic expansion, since the air wouldn’t move up without a temperature gradient, which means that it cannot get colder that the mountains already are. So I would think they are simply farther away form surface heat radiation and have thinner air that don’t assorb heat…

Sorry i didn’t meant to be misleading, just to discuss! However after checking on Wikipedia https://en.m.wikipedia.org/wiki/Lapse_rate I omitted that lower pressure air at high altitude absorb/emit less heat, but what I wrote is not wrong, just incomplete…

Without checking, I would say that it’s because the heat dissipate away from the planet and the hot air will eventually cool down while rising? My understanding is that it’s hot near sea level because it’s where the heat from the sun gets reflected and radiated from the earth surface, correct me if I’m wrong…
