Excerpt from Annales de Chimie Et de Physique, 1858, Vol. 52 Lorsque l'on veut recueillir le gaz, on fait le vide dans le tube au moyen d'une grosse pompe de gay-lussac, muni( d'une petite éprouvette à mercure. On peut ainsi faire le vide à 5 millimètres de mercure. Le tube, vidé d'air, étant plongé dans la crevasse on le remplit en ouvrant et fermant successivement le robinet au moyen dela tige et du levier coudé LL' About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Annales de Chimie Et de Physique, 1833, Vol. 52 Humphry Davy décomposa les alcalis et les terres et obtint des métaux tellement combustibles qu'ils brû lent au contact de l'air et de l'eau. En se fondant sur ces propriétés extraordina1res Davy essaya d'établir une théorie des volcans; il supposa que ces métaux existaiènt dans l'intérieur du globe et que l'eau dela mer ou l'air, en réagissant sur ces masses métalliques si éminemment enflammables occasionnaient tous les phénomènes que présentent les volcans.

Excerpt from Annales de Chimie Et de Physique, 1899, Vol. 17 Or, nous avons quelques raisons de croire que l'hydro gène, comme les autres liquides, doit bouillir à une tem pérature d'autant plus basse que la pression sous laquelle il est volatilisé est plus faible. La question est de savoir sur quel abaissement de température nous pouvons prati quement compter. Nous pouvons nous servir du point d' 'bullition et des données critiques pour calculer une formule donnant la tension de vapeur approximative, en prenant 35° absolus pour point ébullition, 52° absolus pour température critique et atmosphères pour pres sion critique. La tension étant évaluée en millimètres, on a alors, pour première approximation. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
