I smoke. I like to lite cigarets with matches. It was long time since today when I used lighter to light a cigarette. Smoke from the lighter, smoke from the cigar, also smoke of the matches was escaping gravitational pull. I never saw any research made on lighter (synonym) than gravity particles. Is there any?

No there are no know anti-gravity particles, what you are seeing are lighter than air particles.

 

[Drakkith]

The hot air produced by a lighter and by your cigarette is less dense than the surrounding cooler air. This causes it to rise and it carries the particles of smoke with it.

I would still go about that it is worth to check gravity relation of particles for witch it is 'harder'' to leave the atmosphere.

''how hard'' it is for a certain particle to leave gravitational pull of a certain earth☻

The only thing that would leave the atmosphere on its own is Helium. Hydrogen, the lightest element is too reactive and will form compounds that keep it in the atmosphere, and everything else is heavier than Helium or not a gas and will not escape. The particles of smoke will only rise so far before the air loses it's heat and eventually they will fall back down or get collected in rain or something like that.

so nothing can really escape gravity, not even partially?
there is no room for research?

You will not lose hair if you find mistakes only in others
(i found several for miself)

The only way to escape gravity is to provide a counteracting force.

Helium can escape the Earth because the buoyancy from the atmosphere allows it to do so.

Without a counteracting force (that is greater than the gravity) you cannot escape it.

Gravity affects anything that carries mass/energy. It's just that often its effect is weak/negligible because the other forces present are simply stronger.

Without a method of propulsion, like a rocket, an object must have a certain velocity to get out of the atmosphere and escape Earth's gravity. The heavier elements never attain that velocity because of their mass. Helium however is the 2nd lightest of all elements AND is extremely stable. It does not form compounds with other elements which would bind them together resulting in a much heavier molecule.

In addition, anything more dense than air will NOT rise high enough to escape the atmosphere anyways.

No, eventually it would get high enough for buoyancy to become irrelevant. It escapes because it has escape velocity because the velocity of the random motions is higher for lower mass molecules in air.

Well, you learn something new everyday.
