they test for bose-einstein theory with temp something like 1X10^-10 kelvin.
it does prove that all atoms fuse together.
i dont know how but maybe the electrons dont have enough energy to even spin around the nucleus.

there's no way can get -400 lor..even below absolute 0 also can't. AFAIK la..

Just that i cant acess it because i am not a meterial tech student sorry...typo error as i wanted to log off ASAP yesterday... I need CURI CURI get some LN2 , persumablely OC Gang had better idea of finding one LN2 anyway , as usual , need to buy the container . i dont have one  Haha , anyway , Next time if i open a Laboratory , may be i can get them like water This part i dont understand ... -400 C ? if can get , i want , because it is below absolute temperature lol . everything will become Super Conductor By Boss-Einstein Consedant law (This is a state where atom identity do not exist because all molecule can be squeeze into a particullar space , an ultra dense area) , you can merge the whole Petronass Tower into one small Ball They had prove the law by Laser Cooling on some inert gases . Haha , if really -400 C . i think you friends hand will Vanish .... if -400 F , i may believe .. but not -400 C  it's between -200°C ~ similar tu Dry Ice lor...but LN comes in Liquid... btw...u guys watched Demolition Man (Sylvester Stallone n Wesley Snipes), that's LN2 fyi... |

Liquid Nitrogen boiling point is at -145 to -150 deg C.
Liquid Oxygen boiling point is at -183 to -185 deg C. And that depends on pressure around it. Dry Ice only forms when Liquid CO2 is expanded below 4 bar. How I know? I work in EOX (Eastern Oxygen). HEHE |

RM3.80 per kg actually anybody can get the dry ice?i mean individual can get this material? Anybody can buy DI from that place. You just need to place an order a day in advance and pick them up yourself the next day. You also need to bring your own container. This post has been edited by arj: Aug 2 2006, 10:06 PM |

When exposed to the surrouding air, a 1kg block of DI will completely evaporate in less than an hour. Store it in an ice box and it'll last a few hours. The larger the amount you have, the longer it'll last. |
