dhamim ansari Posted April 13, 2013 Posted April 13, 2013 there are three types of Matter they are 1 solid 2 liquid 3 gas My question is solids and liquids are getting attracted towards gravitational force but why gases are not getting attracted towards gravitational force... Plz help me
swansont Posted April 13, 2013 Posted April 13, 2013 Gases are attracted by gravity, which is why the earth's atmosphere is denser closer to the planet.
John Cuthber Posted April 13, 2013 Posted April 13, 2013 Also, if you get a container and empty the air out of it then you can measure the change in weight.Similarly, they sometimes measure the amount of gas in gas cylinders by weight.
CaptainPanic Posted April 13, 2013 Posted April 13, 2013 Bubbles of gas rise in water, because it is lighter than the water. So, to you it may seem like the bubble goes up, but it actually also the water falling down. It is not like the gas is not attracted by gravity. It just has a lower density. If you sit on a seesaw, and a very heavy person sits on the other end, you will go up. But you do not go up because gravity stops working... but a heavy person has more mass, so the force he exerts on your seesaw is just larger. And although this isn't a perfect analogy to gases, it's a bit similar at least.
Przemyslaw.Gruchala Posted April 13, 2013 Posted April 13, 2013 there are three types of Matter they are 1 solid 2 liquid 3 gas Not exactly 3. There are also: 4 plasma (nucleus without electrons which are freely moving) 5 hypothetical quark-gluon plasma (nucleus can't form and sub-particles (whatever they are) are freely moving). But this state of matter is breaking Baryon Number conservation. Surprisingly correctly modern scientists are expecting it with ultra high pressure. My question is solids and liquids are getting attracted towards gravitational force but why gases are not getting attracted towards gravitational force... They are influenced by gravitation. How otherwise clouds of hydrogen would form and create new star?
JohnStu Posted April 25, 2013 Posted April 25, 2013 all things are attracted to gravitational pulls, the gases dont "stick", so it seems like they are not being attracted. also because we dont realy feel 'cause our lungs have atmosphere pressure on the inside

swansont Posted April 25, 2013 Posted April 25, 2013 I was going to mention plasma was forgotten.There's also Bose-Einstein condensates.
