Page 8 - Fahr., the surface of demarcation between the liquid and gas became fainter, lost its curvature, and at last disappeared. The space was then occupied by a homogeneous fluid, which exhibited, when the pressure was suddenly diminished or the temperature slightly lowered, a peculiar appearance of moving or flickering striae throughout its entire mass.
Page 60 - ... been entirely reduced, the tube weighing the same as before passing the oxygen through it. 11. Determine the composition of water by weight by passing dry hydrogen over half an ounce of copper oxide, and collecting the water in a weighed chloride of calcium tube. Show approximately that water contains two parts by weight of hydrogen to sixteen parts by weight of oxygen. 12. Note the first law of chemical combination : that chemical compounds, Mich as water, always contain their components in...
Page 8 - At temperatures above 88° no apparent liquefaction of carbonic acid, or separation into two distinct forms of matter, could be effected, even when a pressure of 300 or 400 atmospheres was applied. Nitrous oxide gave analogous results.
Page 151 - At a still higher temperature it again becomes fluid, and finally boils at 440 C. The density of the vapor then diminishes gradually, until, at 1000° C., a point is reached where it is 32 times as great as that of hydrogen at the same temperature. Sulphur in all its forms is insoluble in water and alcohol, a poor conductor of heat, and a non-conductor of electricity. When heated in the air to 260° C., it takes fire, burning with a pale-blue flame.

Page vii - Such a course of study obviously cannot be undertaken except as the sequel to a series of experimental lessons, perhaps repeated more than once, in which the properties of the chief elements and some of their compounds have been demonstrated. As a guide to such a course no better book could be desired than the...
Page 8 - On partially liquefying carbonic acid by pressure alone, and gradually raising the temperature at the same time to 88° F., the surface of demarcation between the liquid and gas becomes fainter, loses its curvature, and at last disappears. The space is then occupied by a homogeneous fluid, which exhibits when the pressure is suddenly diminished or the temperature slightly lowered, a peculiar appearance of moving or flickering striae throughout its entire mass.
Page 236 - ... soluble in water; alcohol also dissolves it freely, which is the case with comparatively few of the compounds of this base; the solid hydrate of commerce, which is very impure, may thus be purified. The solution of this substance possesses, in the very highest degree, the properties termed alkaline; it restores the blue colour to litmus which has been reddened by an acid ; neutralizes completely the most powerful acids; has a...
Page 139 - The compound resulting from the union of two or more atoms is called a saturated compound, when the atomicity of each atom present is satisfied.
