A joke about the Americans.


Not true... an Oxygen tank is the generic name for a steel tank used in situations that I can't quite remember for purposes that require the user to be able to not die due to lack of air... for you to even attempt to challenge my superior ability to justify the impossible clearly shows that you have no idea (or concept) of what you are talking about! I will on this occassion overlook the fact that you have not referenced any scientific data regarding this discussion and your comments are unsubstantiated hearsay but I must INSIST that you stop trolling these types of threads until you actually start to grasp the detail required in order to fully debate the complexity of the subject matter 





The generic term in this case is in fact: Compressed Air Tank.
Notwithstanding this salient point, your were still incorrect to describe the contents of an Oxygen tank to contain anything except Oxygen, and an acceptable level of contaminants.
Now please, kindly, go back under whichever rock you choose to hide and allow the adults to maintain a more mature conversation.
Oh, and
Ah. I see. Like all the other truly unenlightened and uneducated individuals you attempt to obfuscate the truth by use of an unnecessarily complex justification of your fundamentally flawed viewpoint.

since when did ANY ****** ever say "We're doomed the COMPRESSED AIR TANKS are punctured" ..... never, ever, bloody ever... is the answer to that!Its always been "the OXYGEN tanks are ruptured, now we're fecked" so NOT ONLY are you way off the mark (see fig 1 below):

But it's also clear that you've never watched a single episode of a space or underwater adventure film, and therefore are completely unqualified to comment on the discussion at all.....

Only 21% though
.... the rest (nitrogen, carbon dioxide, argon and smaller amounts of hydrogen, carbon dioxide, water vapour, helium, neon, krypton, xenon, and others) make up the miracle that is "air"....
So if your oxygen tank contained just oxygen it would kill you.... and you'd have one **** of a long face then

Oxygen tanks contain pure oxygen, air tanks contain air (the components of which you summarised above). You don't put compressed air in a tank labeled oxygen, or vice versa, that's the whole point of making the distinction when you label tanks containing compressed gases.
Why would pure oxygen kill you? I used to breath pure oxygen quite often during decompression dives (though never at a partial pressure of over 1.6atm) and I never died once.

Alrigthy then.....

Your blood carries oxygen in two ways, attached to the hemoglobin of the red blood cells and dissolved in the plasma. Each red blood cell carries at max 4 oxygen molecules so increasing or decreasing the pressure won't affect that much, but changing the pressure will affect the amount of gas in the plasma. This has serious consequences for divers but is also how the astronauts were able to breathe 100% oxygen without toxic effects.
At sea level we live at approximately 14.7 psi of pressure from the weight of the air above us (Also known as 1 atmosphere). At this pressure our plasma has a certain amount of oxygen and nitrogen (as well as CO2 and other gasses) dissolved in it. Henry's law shows that if we increase the ambient pressure (the pressure that your body and lungs feel) then the plasma is able to hold more molecules of each gas. This can be serious for divers. If someone dives to 33 feet under water they are at approximately 2 atmospheres, or twice the pressure. Now I don't think the plasma can directly hold exactly twice as many molecules, but it certainly can hold more. Why is this dangerous? If a diver has been under greater than atmospheric pressure for an extended time to allow more gas to dissolve into the blood than suddenly goes from high pressure to a lower pressure, the plasma can no longer hold as much gas molecules and they will form back into a gas (while still in you). This condition is known as 'the bends' to divers. A great example of this is to open a soda can. Soda is under a positive pressure, which allows the pop to hold more molecules of CO2 than when the top is released and the liquid is now at atmospheric pressure and CO2 is released.
So now we have an example of increasing pressure affecting the gas in the blood, but Henry's law also shows that decreasing the pressure will decrease the amount of oxygen in the blood. Here in Colorado we are at 1 mile above sea level (about .75 Atmospheres) and I will have less oxygen dissolved in my blood then you will there in Connecticut. (I believe my body compensates by increasing the number of red blood cells, but don't quote me on that because I didn't look it up). But this is because we breathe the same air with the same percentage of oxygen. If I were to increase the percentage of oxygen, I would soon be able to match the amount of dissolved oxygen that you at sea level would have. At this lesser pressure I will have less total molecules of dissolved air, but a greater percentage of these dissolve molecules will be oxygen. This is how the Apollo space program was able to give the astronauts 100% oxygen for an extended period of time. At the low pressure the plasma in the blood will hold a lot less total molecules than you and I, but nearly all of them will be oxygen, unlike us air breathers with nearly 78% of the total dissolved molecules being nitrogen.
You'd better go and get that pulse of yours checked as I fear you may already be dead

I suspect that we weren't too scared of a tiger tank as no there were no tigers to fill the tanks. Zoo's wouldn't let them out.
Buenas Dias Sal.
Slightly hung over oday (well ok thats a lie, Im actually still drunk, we woke the hostel owners up at 6am to try and get back in
they wernt impressed lol)

Potentially changing me for the worse, depending on which way you look at it. Still trying to find more than 1 other poker player is becoming a challenge though but Casinos are 10 a penny here
