Page 11 - A solid heavier than a fluid will, if placed in it, descend to the bottom of the fluid, and the solid will, when weighed in the fluid, be lighter than its true weight by the weight of the fluid displaced.
Page 184 - On partially liquefying carbonic acid by pressure alone, and gradually raising at the same time the temperature to 88° 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 dickering stria* throughout its entire mass.
Page 193 - ... other salts. On one diagonal the solubility of its, neighbours is lower, on the other higher than its own. In its column the solubility of its neighbours is higher, in its line it is lower than its own. In compartment (b) of Table V we have the values of S, the specific gravity of the mother-liquor at T, referred to that of distilled water of the same temperature as unity. These numbers cannot. as they stand, be compared with each other because they refer to solutions of such different concentrations....
Page 11 - Proposition 5. Any solid lighter than a fluid will, if placed in the fluid, be so far immersed that the weight of the solid will be equal to the weight of the fluid displaced.
Page 196 - ... takes place. In the second compartment (b) we have the values of D, or the specific gravity of the salt in crystal at T, referred to that of distilled water of the same temperature as unity. The data in this compartment are in most cases for different, but always neighbouring temperatures.
Page 11 - If a solid lighter than a fluid be forcibly immersed in it, the solid will be driven upwards by a force equal to the difference between its weight and the weight of the fluid displaced.
Page 197 - ... whilst the displacement of the liquid is the same at the end of the operation as it was at the beginning. In thus describing the preparation of the saturated solution, we have described an operation of substitution. It is therefore permissible to regard solutions as products of substitution. If we give to the above numbers their molecular interpretation, we see that the mean apparent displacement of one molecule of caesium chloride in its saturated solution at 23-1° is equal to that of 2-723...
Page 184 - 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 11 - Proposition 3. Of solids those which, size for size, are of equal weight with a fluid will, if let down into the fluid, be immersed so that they do not project above the surface but do not sink lower. If possible, let a certain solid EFHG of equal weight, volume for volume, with the fluid remain immersed in it so that part of it, EBCF, projects above the surface. Draw through...
Page 11 - Proposition 2. The surface of any fluid at rest is the surface of a sphere whose centre is the same as that of the earth.
