翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ammonia fountain ： ウィキペディア英語版 Ammonia fountain The ammonia fountain is a type of chemical demonstration. The experiment consists of introducing water through an inlet to a container filled with ammonia gas.〔''The Ammonia Smoke Fountain: An Interesting Thermodynamic Adventure'' M. Dale Alexander , Daniel T. Haworth J. Chem. Educ., 1999, 76 (2), p 210 〕 Ammonia dissolves into the water and the pressure in the container drops. As a result more water is forced into the container from another inlet creating a fountain effect. The demonstration introduces concepts like solubility and the gas laws at entry level. A different gas of comparable solubility in water, such as hydrogen chloride, can be used instead of ammonia.〔L.A. Ford, ''Chemical Magic'', 2nd ed., Dover, 1993.〕 If the ammonia is replaced by a liquid vapor, such as water vapor, at a pressure higher than its room-temperature vapor pressure, a similar effect is produced. In this case, the reduction in pressure in the container is due to condensation of the vapor as the container cools to room temperature. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ammonia fountain」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
