why most gas has an upward direction?

gas has lesser density than air.. elem. science hehe

sa akong nabal.an, dili gravity ang ga.work out diri sa earth..matud pa ni lolo albert, gravity is the main reason why the planets are revolving around the sun and keep rotating on their axis...same principle that applies here on earth considering that earth has its own gravitational force as well...later, some physicysts were saying that lolo albert was wrong, though he's right in some point..they said, the reason why objects here on earth is reacting to each other is because of quantum mechanics...its a combination of ions nga naay positive og negative charges og electomagnestism..they said, gavity is working at large objects like the solar system og dri is earth, its quantum mechanics...right now, they're trying to figure out how to come up with one equation out of these two forms..kamo nay search kay masunggo kog inexplain hehehe..

because gases has lesser density compare to other matter i.e. solid or liquid etc. which is true, the more denser the matter is the greater pull is applied.

Correction!…si lolo Isaac diay nakadiscover sa gravity hehehe..then si lolo albert nay giusab sa law of gravity nga lahi sa concept nga giingon ni lolo Isaac..ingon siya, speed of light ang nay pinakadakog contribution og nganong ang planets mu.revolve around the sun..then later on his studies, nadiscoverd na sad ni lolo albert nga ang mga planets including the sun are just like moving in an imaginary soft fabric of space and each of the planets are moving in a curve on this imaginary soft fabric caused by the sun’s presence..sama sad kuno ang nahitabo sa earth kay naa man say kaugalingong gravitational force ang earth..pero ingon sa mga physicists, ang earth is composed of matters and this matters is composed of millions of atoms..ang outside shell sa atom is negative charges of electricity...then tanan object dri sa earth has something to do with the magnetism..so, ang quantum mechanics is a combination of atoms and electromagnetism…they try to unify this quantum mechanics and gravity to come up with one equation but it seems like ang gravity is dili jud masagol sa quantum mechanics…so mean, gravity is working lng daw kuno sa large objects like sa outer space then and dinhi sa earth, its quantum mechanics, not the gravity..

in connection sa topic, mostly sa mga gases is less ang atoms kaysa ordinary air..so ang air will keep repelling this gases and the reason nganong musaka sila,..

hehehehe...diri ko gusto makakuhag answer dili sa google. kay maglisud pud ko kung unsa2x na mga keywords akong ibutang...

+1 ko ani...

The answer is very simple. Mo disperse man ang gas. Dispersion is defined as the movement of a certain gas or particle from a more concentrated area to a less concentrated area. We all know nga "thin" ang air sa ibabaw, so nature would cause the gasses to go upwards.

pareha2 ra guru ug theory sa tubig ug grasa?

mga bossing, ask lang ko, nganong ang kasagaran sa mga gas is upward man ang direction while ang uban matter downwards?

i know mosulti mog tungod sa gravity, pero pasabot ba ana nga in nature all matter is in outwards direction from earth?mao inwards ang direction sa tanan solid/liquid matter tungod kay magunitan pa sa gravity while ang gas dili na.... so unsa man jud?

is not about the gravity,, its because of its density..

gas properties has no shape, and its because of its density they float on the air..
now if your asking why float upwards, its because some of the gas can be affected by heat that can affect their density..

for example: ang air nato kay gas na ni, 1.225 kg/m3 while helium gas is 0. 1785 g/ml

the golden rule for this is the lighter the higher tendency to float on the air..
is also the same on water,, the higher density the higher tendency to float on the water..

maau ka ts ky nka pangutana ka ana. nka kuha kos imo pasabot.
allow me to expound. Para nku, sa layman's view, mka wonder jud ta nganong mulutaw man ang gas nga naa man untay gravity? eapply nato sa scenario ha by altering tangible objects:

helium = 1 pc paper
air = 1 sack of rice
gravity = human pulling force
human body = earth surface

given above, of course we can conclude that we can pull the paper towards us much easier than the sack of rice. but it doesn't work that way. Regarding sa GAS floating, there are many things to consider like temperature, air, pressure and other forces and elemental reactions. siempre kung mag init ka og tubig, water expands and so does air and the less denser particles goes up by that reaction.

another impossible experiment in my mind:
suppose we can see and hold helium gas, now inside a tube, there's no presence of other particles/elements but there's still gravity, we put the helium into it.

the question is, will it float upwards or sink to the bottom surface of the tube?
