Sivu 29 - ... added, we are furnished with the weight of a bulk of water equal to that of the lighter solid, and have the data for calculating the specific gravity by proportion, in the usual manner. (22) Hydrometer. — Another method of taking the specific gravity of liquids, consists in the use of the instrument called the hydro- la' ' meter or aerometer.* The hydrometer (fig.
Sivu 353 - In two circuits producing equal electro-motive (or voltaic) effects, the sum of the electro-motive forces divided by the sum of the resistances is a constant quantity ; ie, ^ = ^-| : if E and R be proportionately increased or diminished A will obviously remain unchanged.
Sivu 123 - PNB the angle of reflection formed between the same perpendicular and the reflected ray. The law which regulates the reflection of light is expressed by saying that ' the angle of reflection is equal to the angle of incidence ' : the incident and the reflected ray are always in the same plane, Fio.
Sivu 106 - The same number of atoms combined in the same way produce the same crystalline form, and the same crystalline form is independent of the chemical nature of the atoms, and is determined only by their number and relative position.

Sivu 231 - It must be borne in mind that equal bulks of different liquids produce very different volumes of vapour. Water furnishes, bulk for bulk, a much larger amount than any other liquid, a 'cubic inch of water at 212° expanding to nearly a cubic foot of steam at 212°, or more accurately to 1696 times its volume. The following table shows the volume of vapour which is furnished by a cubic inch of four different liquids, at their respective boilingpoints.
