謝謝你的回答  感覺還是怪怪的 但也無法判定你的答案對不對 小弟認為氣球重至少也要0.1g 百貨公司的氣球頂多2~3個2000cc可樂瓶的體積

1.又算錯了喔, 1公升=1000cm^3 2.氦比氫貴 此文章於 2008-01-20 06:01 PM 被 TRG-pro 編輯. |

1.....重算... 氫氣密度為0.085KG/M^3 空氣密度為1.2255KG/M^3 1.2255-0.085=1.1405 KG/M^3 =>1140.5 G/M^3 =>0.0000011405 G/CM^3 1CC=1CM^3 1000CC的氫氣..浮力是...0.0011405 G/CM^3 (應該沒錯啦...我是用1000CC當基準...) 2.....http://www.ilovetaipei.com.tw/830202.htm 如以六米鋼瓶盛裝的氦氣和氫氣比較，前者價格約在二千至三千元，後者約是五百至八百元 原來如此.... |

氫氣密度為0.085KG/M^3
空氣密度為1.2255KG/M^3 1.2255-0.085=1.1405 KG/M^3 =>1140.5 G/M^3 =>1140.5 G/(100cm)^3 =>1140.5g/1000000cm^3 =>0.0011405g/cm^3 1CC=1CM^3 1000CC的氫氣..浮力是1.1405 g, 也就是每1000cc提供約1g的浮力  |

在第21集裡有 It would require such a large number of balloons (3500) to lift an average (44 lb.) 4 year old girl just a few feet off the ground that there is no way the myth could have happened unintentionally. http://en.wikipedia.org/wiki/MythBu...29#Carried_Awayhttp://en.wikipedia.org/wiki/MythBu...29#Carried_Away |

在Pilot 3 裡也有
Adam Savage went up in the MythBuster's rig, which was a lawn chair with 16 plastic weather balloons attached, and went up to the maximum height that could be obtained with the safety ropes attached, 75 feet (22.5 m). He safely descended by shooting out some of the balloons. The actual event behind the myth was verified by documents provided by the FAA. http://en.wikipedia.org/wiki/List_o...C_Goldfinger.22 每個氣球的氦氣量約33立方呎 |
