Ah, no. The Earth's gravitational field provides exactly that. It pulls gas molecules to the planet. Yes, some escape but the majority are kept tight to Earth.
Consider the Sun. it is a big ball of gas. Why then doesn't it all evaporate and the Sun become smaller and go out? Because the gravitational field creates, effectively, an invisible 'force' container.
Where is the earth's gravitational field? I would like to see some proof of this existing. Also why does helium rise up when earth's gravity supposedly pulls molecules down?
It appears you're saying there is no gravity.
Really then, either you're a troll or incredibly dense. Perhaps you're made of lead or neutronium, or a Biden voter.
As for <Also why does helium rise up when earth's gravity supposedly pulls molecules down?>
Ask why does ice float? After all, it's water too.
The answer is density.
Helium is the second element on the periodic table... that makes it’s atomic mass very small compared to other gases like Oxygen and Nitrogen. Are you a business major?
Earth gravity affects all atoms. So one of the forces acting on helium is gravity.
In a mixture of gases in a g-field, it is correct that density will allow an on-average height separation where the lighter atoms or molecules rise. In an environment like the ISS, gases actually will not separate by density. Around Earth though, yes, helium will rise to the exosphere as g-force contests with diffusive gas pressure force on helium atoms. G vector points to Earth, but the gas diffusion being thermodynamic, it's statistical as atoms bounce off each other, so the force is a 3 vector. That means the atoms not only rise but move around in the X and Y axes in the air. The entropy is very jjggly in that way.
As for me, my B.S. in Physics was from one of the best science schools in the US. If you have some science issue to discuss, bring it.
