Physics any evidence of water in gas?

You guys know that EV's are not exactly new, right? Just now they are widely commercially available.

They had EV's back in 1912 ;)

That's sick. I'd be angry if it wasn't so cool, that we've been guzzling for so long

If you are talking about gasoline or petrol, then yes it has trace amounts (.05 to .1 percent by volume) because at least some of the additives, including ethanol absorb water. It is intentional in order to keep engines from sputtering. This is exactly why some people add a special antifreeze in winter to keep their gas lines from freezing in winter.

It's a good source of OTC methanol. Should be distilled before use as they add a non toxic bittering agent.

That air is in a space. One Gas is not inside of the other gas. They are beside each other in the space.
Correct me if I'm wrong.

i think your issue is a semantic one. you are correct in a literal, spatial sense.

air is, as you note, a homogeneous mixture of independent gases. so, for example, water vapor molecules are not inside nitrogen molecules - they are in the empty space between them.

so the discussion hinges on your definition of the word "in".

when we say that water is in the air, it means the atmosphere as a whole. it's well understood, and it's not inaccurate to say it.

Kind of sweet of you to be entertaining that mega idiocy and trying to be pedagogical about it.

I struggle to see how he is "correct" though. None of the compounds that make up air "are" the air itself and molecules never exist "inside" other molecules. It's just a total miscomprehension of basic chemistry, put forth with an absolute lack of humility.

OP can't even tell atoms and molecules apart.

I mean this:

I think about how atoms are arranged on and between each other when discussing these things.

...is the fucking answer to your post or what? Roflmao

Again it's kind of you to be this patient with such a ridiculous question.

maybe english is not their first language. i don't know.

It's not about language. The whole thing is a delirious mess designed to confuse. Like trolling without humor.

Why make the thread about whether there is water in air (a well known fact) if the only point is to say that one molecule isn't "inside" of another molecule (something that nobody believes)?
