Absolute Zero

i was just polishing up (cramming my ass off) for the sat2's i'm taking tomorrow, chemistry among others, and i was reading a little tidbit about absolute zero
its really cool to think about
absolute zero is the theoretical temperature that is so cold that matter ceases to move
also, since gases decrease in volume as temperature decreases, gasses would not exist pretty much
anyone know of any work concerning this? i found it pretty cool |

from what i know, absolulte zero cannot be achieved in any way without the use of some kind of "force Field" because the only conventional way of testing temperates is containment, which will be affected by the heat outside the container, etc etc etc.
i think if anyone could acheive absolute zero, it would continue to freeze everything surrounding it and continute all the way until the earth is simply frozen. |

Not being particularly well versed in physics or thermodynamics i would have to say that's a pretty bent concept. Heat transfers through mediums as they "approach" equilibrium. This is how heatsinks, vented discs etc. work on the concept that you can transfer the heat from a medium faster by increasing surface area, and how much "colder" air it comes in contact with. Basically, absolute zero is impossible because anything will disturb the rest of atoms making it no longer absolute zero (only a very very small bit away), no amount of insulation is 100% effective, so no matter what you have some heat leakage, making abs. zero, even in the remote recesses of the universe (which are cold beyond comprehension), impossible, and make the concept on earth simply laughable.
I'm taking the SAT I tomorrow :rolleyes: :rolleyes: :rolleyes: :rolleyes: |

first time taking them?
(i've already taken the sat 2's once, not a good day. woke up late and didn't have time for coffee, didn't eat anything, didn't sleep well, then took three ing tests. omg my brain was mush) |

"And this question is for the kid with leukemia. Is there anything lower than absolute zero?"
"How about my white blood cell count?"
Gotta love Family Guy :D :D |

Where do you come up with this stuff? |

Yeh, first time... I'll do fine i gather though.. =) being there at eight is kind of hellishly cruel, i can barely drool at that time of the morning, but no matter, i've taken tests under far more impaired conditions and fared well.. |

i know!!!
chem is so last year
just i'm taking the test again this year cause i did ty last year :( |

In case anyone's interested, as of a month ago, the world record for coldest temperature ever recorded is held by MIT scientists who cooled a sodium gas to 0.5 nanokelvins -- half-a-billionth of a degree above absolute zero.
