Page 963 - Remove for a single summer-night the aqueous vapour from the air which overspreads this country, and you would assuredly destroy every plant capable of being destroyed by a freezing temperature.
Page 188 - D into the lower globe, and expels the air, which is forced into the upper globe. The air thus compressed acts upon the water and makes it jet out through the shortest tube, as represented in the figure.
Page 164 - The general laws of gas-absorption are the following : I. For the same gas, the same liquid, and the same temperature, the weight of gas absorbed is proportional to the pressure. This may also be expressed by saying that at all pressures the volume dissolved is the same ; or that the density of the gas absorbed is in a constant relation with that of the external gas which is not absorbed. Accordingly, when the pressure diminishes, the quantity of dissolved gas decreases.

Page 8 - The tenth part of a grain of musk will continue for years to fill a room with its odoriferous particles, and at the end of that time will scarcely be diminished in weight.
Page 139 - Fig. 91. diameter, the edges of which are made to fit tightly, and are well greased. One of the hemispheres is provided with a stopcock, by which it can be screwed on the air-pump, and on the other there is a handle. As long as the hemispheres contain air they can be separated without any difficulty, for the external pressure of the atmosphere is counterbalanced by the elastic force of the air in the interior.
Page 296 - Specific gravity is the ratio of the weight of a certain volume of a substance to the weight of an equal volume of water. For liquids of limited solubility, the specific gravity will predict whether the product will sink or float in water.
