Uh, isn't 'gel' another state of matter?

Bold text i have gas

Removed the following: "(Incidentally, these phases correspond to the four basic elements distinguished in Antiquity: earth (solid), water (liquid), air (gas) and fire (plasma))." That's just silly. It's incredibly anachronistic (do you honestly think the ancient Greek had knowledge of plasma?) and it's not even technically correct - the four elements are made up of four properties - hot, wet, dry and cold, which arguably correspond far more closely to the states of matter anyway.

I think there should be a link to four elements somewhere, either in this article or in the disambig page. Something like "Gas is one of the four classical elements". --Stevage 14:21, 3 December 2005 (UTC)

But it's not one of the four classical elements! (unsigned, anon)

That's...a good point. Stevage 21:02, 4 December 2005 (UTC)

Can you tell me about why the gas prizes are so high?

[edit] More about use?

Shouldn't there be a section about the use of gas here, the growing importance of gas (for instance for heating etc.) and domestic uses? --Vikingstad 23:45, 21 November 2005 (UTC)

Ah, nevermind, I suppose the See Also link to Natural Gas is good enough... --Vikingstad 23:50, 21 November 2005 (UTC)

[edit] water vapor

1st para: "which will then boil or evaporate to become a gas (e.g. water vapor)" Surely water vapour is not a gas, but particles of water suspended in air? Water in its gaseous state is Steam, an invisible gas which can only be produced under presure.

Water vapor is the gaseous form, usually used for conditions below the boiling point. Stream is water vapor at or above the boiling point. At least that has been my understanding. Thanks, Vsmith 13:12, 9 January 2006 (UTC)

[edit] Definition of gas

The article lacks a more precise definition of gas (i.e. how can I know if a substance is in a gas state?). The article cites many properties of gases, but does not say which of them (if any of them) completely characterizes a gas. I don't know if there is a generally accepted definition, in case there is more than one we could write a discussion paragraph comparing them. I've seem somewhere that gas is a state where matter occupies any container. That is a very simplistic one (and formally wrong, I believe), does someone know a more technical definition? I like the fire article, maybe we could use it as a parameter for quality. Rend 01:06, 20 April 2006 (UTC)

[edit] No intermolucar forces?

In the gas phase, the atoms or molecules constituting the matter basically move independently, with no forces keeping them together or pushing them apart.

I thought there still are intermolecular forces, but that these forces can be neglected in the gas phase, especially when the gas is considered as an ideal gas.

[edit] Why are the gas prices so high?

Because Uncle Sam hasn't really done much in the search of alternative energy sources. How about solar 

power? Dont hear much about that, and the sun is on a stringent and dependant time schedule! Very dependable! Something is fishy. Forget the other countrys, center on America. Wait a second.... We are in debt and most our investors are foreigners... There is nothing we can do to become dependant because We would ween ourselves off the other countrys that are investing in this country. We will, as a group, never become independant with our own system of fuel... The saudis, or whoever owns the oil, own us.

How do I know this? Because many years ago, I devised a simple soulution for a diverse system of 

ecomical fuel supply partly involving the wind and sunlight. Shortly there after, some men in black came to my door and destroyed everything! My complex blueprints for a stronger America went down the

drain. 
The conspiracy involves very rich people investing in other countrys. Mostly polititians, the people who

alledgedly work for the Americans in this country. The foreigners are supposed to be second to us. Maybe we just aren't vocalizing our concerns loud enough. The men in black told me, the real solution is easy, start riding a bicycle. I was so mad.

[edit] Common type of gases

Would flatus be considered a trace gas, or what? Or should it have its own listing under "types?" --Jay (Histrion) (talk • contribs) 20:05, 28 December 2006 (UTC)
