question.
K: question
K: would don’t sky divers get the Benz while sky diving if the pressure’s changing from the sky to the ground and they’re going really fast?
K: do you know?
Me: answer.
Me: the bends you mean
K: yeah
[Snip, snip... I removed the part of the conversation where I explain what "The Bends" are.]
K: so, essentially we’re make up of dry ice?
Me: especially if they’ve been scuba diving
Me: then the nitrogen in their bodies would start to bubble out
Me: but
K: isn’t that whas liquid nitrogen is?
Me: they have to go really high
Me: um.. no, and no.
Me: dry ice is carbon dioxide
K: oh
Me: and liquid nitrogen is.. liquid nitrogen.
K: hmm
K: isn’t that the stuff they freeze warts off with?
Me: maybe?
K: oh ok
K: I think so
Me: i dont know what this has to do with your question
K: oh, I just recognized liquidy nitrogen
K: then started to think of another question
K: hmm
K: ok, so air turns to liquid when pressurized
K: then it needs time to turn back into air
K: on the way up?
Me: no
K: oh
Me: nitrogen, in the air
Me: dissolves into your body
Me: when pressurized
Me: and when you depressurize
Me: then if you don’t do it slowly
K: oh ok
Me: then it the bubbles that form are too big
Me: and then they cause problems
K: so, you need time to get the nitrogen out?
Me: exactly.
Me: if you come up more slowly
Me: then the gases can get out of your body without causing bad things.
K: ok
K: like farts?
Me:

LOL. Benz … haha.
High school gas laws. What was it? PV = nRT.
Actually no. That had nothing to do with dissolved gases. I don’t remember the name of the law that said more pressure means more gas dissolves into the liquid. There was a law like that though. I’m gonna call it the Dennis Law from now on.
