why most gas has an upward direction?

kung density ug dle gravity, why mulutaw mang ang tao sa space nga walay may gravity didto?

So I think it's because of gravity?hihihihi


naglibog ko gamay?lol

less dense with gravity = floats

denser without gravity = still floats

naa man gravity sa space.. gamay lang so factor silang duha..


brighta sa mga taw d-i dri sa istorya ko.. abi nako para bugal2 rani dri.. hahaha

I think tungod sa sa density sa gas, Kung bug-at kaayo ang gas mao nang mo paubos gyud tungod sa gravity, but tungod sa kagaan pud sa gas mo pa ibabaw sila, adto na sila magpundo sa mesosphere ba to ang pinaka ka gaan, dili ko sure. gi discus ni namo sa chemistry 2

tungod na' sa upward force...buoyancy...

Hot air rises, cold air sinks. Mas daghan mga hot air sa atmosphere run

Gas molecules has the least molecular density, which causes to let the Centripetal Force, or Gravity from the earth got a hard time of bringing it down...Now try to imagine the balloon and Cotton...Both have the very small amount of weight.. But the difference is, the cotton's molecules are more compact than the helium(WHICH HAS A HOT MOLECULAR TEMP) inside the balloon(with is very light and has lesser molecular density)..

What if it has OXYGEN inside?
Well its because they are a little bit dense... THERE ARE NO FORCES COMING FROM OUTSIDE WHICH CAUSES TO LET THE AIR GO UP..

note: HOT AIR GOES UP,COLD AIR GOES DOWN...

WELL... you just really made your brain confuse..

do you know what WEIGHT means?
well, got to answer that... weight is the amount of gravitational force applied from a heavenly body or an object...which causes us not to float

so lesser weight= greater tendency to float...

actually, in outer space, where its already out of earth's atmospheric level, which causes us not to be caught from the gravity...Have you ever wonder.. that all the heavenly objects from outer space, that would be landing our earth is burning?

Its because its heavy which causes it to be attracted from the earth's gravity and gets burned because of the collision between O3(ozone layer) and the heavenly object...

even though its very dense...but with out gravity...so..how could that object not float? like asteroids...

since gravity is the very main cause why objects go down...

Remember.. density is a factor which affects the gravitational force(whether it floats or not)

and by the way... DENSITY and GRAVITY are one of the factors which causes
