we evacuate large vacuum chambers (in Earth's gravity) thousands of times per day. NEVER does some gas stick to the bottom 🙂

100% applicable

Also I don’t think a tennis ball is comparable to any earth

gravity cannot hold a gas against a vacuum

Hmmm

we prove that thousands of times per day

Part of the gas indeed leaves earth mayby

if that were true, NASA could not evacuate their large vacuum chamber 🙂

But a very small part

ok

🙂

I tried

it's not the same kind of pressure you're describing... gas can exist in a vacuum chamber.

nope. I've worked with vacuum chambers my entire career

if gravity held gas back, our chemical reactions would never have worked

it's ridiculous

gravity doesn't hold gases down. fullstop

gravity = duct tape for heliocentric model

Hmmmm this looks interesting

apply liberally where needed to cover gaps in science

We gata take you to space

lol

here's a hypothetical: you have a vacuum chamber and introduce some gas. It sinks to the bottom because there's nothing to keep it buoyant. That bit of gas on the bottom of the chamber has a teeny tiny bit of weight and exerts a teeny tiny bit of pressure because of it. THAT's earth's atmospheric pressure.

If you are right I should just quit university lol

But you prob aren't and i am just too dumb to figure out why sorry

@Drewski4343 it never happens. the gas always expands to fill the space...and eventually leaves the chamber. we do this thousands of times per day

it's not true

And if a force is pulling it back?

What about the equilibrium?

No reaction is 100%

But this prob isn't the right question

smoke is a particle. not a gas

you know that right????

smoke is both gas and solid(or liquid, forgot)

um gases are particles too...

the white stuff you see are particles. it's called multiple scattering

anyway, they'd behave the same way

they are solids.

they are not in the gaseous state

they are just small. you can even filter them 🙂
