Weird physics / chemistry curiousity.
I work with liquid nitrogen alot in my line of work. When surfaces
are super-chilled, there is no risk of those surfaces transmitting an RNA-degrading protein to my precious samples. After the parts of machine with said surfaces are done doing their thing, I have to instantly wash and rinse them in distilled water (per manufacturers instructions, risk of rust due to steel type or something)...so these parts are still extremely cold. When I so much as put the parts near a water source, it's almost like they act as a condensor for gas, as alot of gas will collect and eminate from the part. It got me thinking...so I took of my gloves and hovered my hand (wet with condensation and oils n'stuff I guess) over a tub of liquid nitrogen...and the same thing happened. Same thing will happen with an aluminum cage when I place it in a dry sink... What is going on here ? Obviously these materials aren't releasing gas. I'd say they're acting as a condensor due to the cold temperature of the material...but the same thing happens with my hand. Just curious. |

Your hands and water sources are emitting water molecules all the time. In any population of atoms, there is a distribution of energies and some number of molecules at any given time will have enough energy to break free of the mass. If you're in close proximity to a cold enough object, then it is going to chill the air immediately around it and almost immediately after leaving the surface of the water (or your hand) those high energy water molecules will lose their energy to the chilled air and start colliding into tiny water droplets: the "gas" you see. -- Alan Baker Vancouver, British Columbia http://gallery.me.com/alangbaker/100008/DSCF0162/web.jpg |

The cold chills the air and then the air can't hold as much humidity. It condenses into a fog. This signature is now the ultimate power in the universe |

I believe you are exactly right. When the air temp is cooled the humidity rises and when it goes over 100% the water vapor condenses into fog. BTW do NOT take off your gloves near the liquid nitrogen, but I think you already know that. Vote for Palin-brown in 2012. repeal the nightmares.

This explains everything. You apparently took off your diapers and hovered your package over liquid nitrogen, and froze them off. Hey, got any comment on your buddy Brain Fried Bob pppppppuuuuuusssssssyyyyyyiiiiiinnnnnngggggg out when I was in Utah? You sure talked a whole bunch of **** last year when you pppppuuuuusssssiiiiiieeeessss challenged me to a meet when you had a month's notice I would be out of town. What's that? Silence again? Sorta like tennis? BWHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA HAHAHAHA |

This signature is now the ultimate power in the universe Yeah no worries...I'm experienced around the N2. It's all good. Alan's explanation makes sense. Thanks ! |
