Sorry if I sounded arrogant or something, it wasn't the intent. I still think it's impossible to get it from just PV=nRT.
And THAT would be why I am not a science major. FAIL. apologies.
No problem.Not at all! It was a joke. I think you're right anyhow.
<I>May I ask why you bought an O2 tank?</I>
It was cheap, LOL.
But what got me looking for one in the first place was I was on my way home from best buy and there was apparently an accident. In most cases, I don’t stop, unless someone is seriously hurt. (I mean, come on, 911 will be there in a few minutes.) But this one I did.
There was a small kid in the middle of the road, apparently hit by a car, with a pool of blood under him, coming seemingly from his head.
An off-duty nurse pulled over with me. He had his ABCs, but wouldn’t ackowledge us in the slightest. Just groaned. So we basically could only control bleeding and hold Cspine.
Normally I have some medical stuff in my car, but I recently took it out to inventory it. And I kept thinking of things I could do. I went on ebay to find jump bags (I’d been planning on doing this anyway, the event just encouraged me to do it that day) and I saw an O2 tank. Had I had that, I coulda’ popped the kid on some O2.
Had it not been a kid, I probably wouldn’t have taken it as seriously. He couldn’t have been more than 9…10 at the most. (I have a soft spot for kids.) So I almost didn’t get it. I was like “When am I ever gonna really need it?” which I answered with “On days like today?” I wasn’t gonna drop a whole bunch of money on it, but it was less than fifty bucks…so…
<Oh, always. First rule; scene safety. =P I used my POV on an angle to block the scene as best I could (considering it’s only a mustang) and moved it when I heard the sirens coming close to the rig to park there.

I own my own O2 bottle. I bought in new from Galls many years ago. It came in handy a few times. I've left my O2 bottle in the trunk many winters and have not noticed any problems with it.
My only concern is what the extreme cold may do to the metal in the regulator over time. Will it cause some calibration issues with proper liter flow? I'm not sure. I no longer keep it in my vehicle anymore, however.
No, but they function test them. Just about any dive shop, or whoever does the hydro can do a functional test on the regulator-- essentially measuring the literflow output.
Why would you think anyone would buy an oxygen bottle and even consider getting it filled with anything other than medical grade O2? I've filled mine with the O2 cascade system at the department I used to work and have taken it to a place that deals strictly with medical oxygen supply.
