View Full Version : This has been bugging me for a while... Warm & Fuzzy 03-06-2003, 06:23 PM Okay, so, can someone tell me why hydrogen balloons shrink in the cold (winter--outdoors) and then when you go indoors, it "magically" inflats to it's normal size again? What happens to the hydrogen when it's cold... and where does the air come from to fill it up again? No, this isn't homework. ;) Chad22 03-06-2003, 06:24 PM Magic :D Chocoholic 03-06-2003, 06:25 PM A wizard does it :D Warm & Fuzzy 03-06-2003, 06:26 PM Ha-ha, you guys. Georgia's on my Mind 03-06-2003, 06:30 PM i think hydrogen contracts in cold because of it's bonds to each other...(it's a bent linear i think) so when it's cold it causes it to all contact closer...and when its warmer they expand brownsocks 03-06-2003, 08:13 PM Originally posted by Georgia's on my Mind i think hydrogen contracts in cold because of it's bonds to each other...(it's a bent linear i think) so when it's cold it causes it to all contact closer...and when its warmer they expand i think that more or less it. when something is cold the particles don't move very much because there is no heat for energy. when something is warm the particles have more energy so they can move a lot faster and then they take up more room because they are all over the place TJL 03-06-2003, 08:38 PM Ummm...Well, Hydrogen is a gas... Look, could you ask me something about TV? My head is starting to hurt. ;) Warm & Fuzzy 03-06-2003, 08:38 PM Makes sense. So.... Is this only with hydrogen? How come when you fill a balloon with carbon dioxide it doesn't shrink? Or rather, how come it's not as noticable?

I feel better now. ;) Bootsy Whoosh 03-07-2003, 06:15 PM Well, first off, I'm sure you mean to say helium balloons as hydrogen is a very flammable gas and they wouldn't just go around filling up birthday balloons with it. (Remember the Hindenberg?) ;) I think the same would be true for all gasses, but to varying degrees based on the properties of the gas.

Finally, it all makes sense. :lol: Jersey Girl 03-07-2003, 11:44 PM All gases are 22.4 L at STP! I can tell you that much!! (can you tell I had a chem test today?!)

I hate chemistry.:mad: Last term, I was taking both biology and chemistry at once... that was nuts! Good thing they fixed up my program a bit this time around. :crazy: |
