High pressure pushes
@the21cat RIP I thought you were a flat earther lol
I was trying to get you to admit that there could be a pressure gradient
it was way easier than expected... but then you're not a FE
FE'ers, how long does it take to fly from Argentina to Australia?
21 cat. Yer loonier than a 3 dollar bill
a pressure gradient indicates a container
every container of pressure has a gradient
why would we deny the pressure gradient when it is characteristic of a container?
lmao gas fills its container so why would there be a pressure gradient in a container
it should be constant
and it isn't constant on earth because we're not in a container
but it's not lmao
¯\_(ツ)_/¯
literally all pressurized containers have a gradient

The pressure gradient would be in any container that is in a gravitational field. It's just that in most situations, the gradient in air is too small to worry about and it is ignored.
You can determine the gradient the same way you do pressure underwater. You just multiply the depth of the fluid by the density. For very large columns, the density of air would vary. But for a small container, we can assume it's nearly constant, around ρ=1.225kg/m3
That means near sea level, if the pressure at the bottom of a container is 1atm or about 1013mbar, the pressure 1m higher would be less by the weight of that amount of air.
ΔP=ρgh
ΔP=(1.225kg/m3)(9.81m/s2)(1m)
ΔP=0.12mbar
1m up in your container, the pressure is less by about 0.01%.
huh
that's actually kinda illuminating
it shows that even with constant density atmosphere, you could get a pressure gradient
imagine having to prove we aren't in a container
"second law of thermodynamics!"
I mean actually proving it’s existence
what is this debate about
Wether there is a dome or not
It’s not really a debate at the moment
ok what is your opinion
No existe
ok i guess we have nothing to debate about xd
Lol
If we were in space all the air would be gone
It isn't gone thanks to gravity
@Citizen Z how come?
Entropy
Entropy is the reason we have a pressure gradient
I don’t think you understand entropy citizen
@Citizen Z so because of the dome, we have a constant pressure everywhere on the planet not matter the altitude?
Even with a dome, there'd be a pressure gradient. Atmospheric pressure is caused by weight of the atmosphere, so the higher your altitude, the less pressure would be exerted on you.
buoyancy and density would not explain a pressure gradient.... only one thing would explain that...
Buoyancy requires gravity
shhht they don't know that :P
