Page 335 - The total energy of any material system is a quantity which can neither be increased nor diminished by any action between the parts of the system, though it may be transformed into any of the forms of which energy is susceptible.
Page 20 - The difference between the number of the lowest member of a group and that immediately above it is 7 ; in other words, the eighth element starting from a given one is a kind of repetition of the first, like the eighth note of an octave in music.
Page 53 - Avogadro's law states that equal volumes of all gases at the same temperature and pressure contain the same number of molecules...
Page 45 - To form some conception of the degree of coarse-grainedness indicated by this conclusion, imagine a rain drop, or a globe of glass as large as a pea, to be magnified up to the size of the earth, each constituent molecule being magnified in the same proportion. The magnified structure would be coarser grained than a heap of small shot, but probably less coarse grained than a heap of cricketballs.
Page 115 - ... the ratio between the sine of the angle of incidence and the sine of the angle of refraction is a constant, depending only upon the nature of the two media.
Page 13 - ... an equal number of atoms in the molecule had the same, or very similar crystal forms. Mitscherlich concluded at first that it was only the number and not the nature of the atom which conditioned the crystal form. Later, he recognized that the way in which the atoms were united in the compound was an important factor in determining its crystal form, and then arrived at the generalization that, "An equal number of atoms combined in the same way produce the same crystal form, and that the same crystal...
Page 547 - A' and B' be p' and q', and the affinity coefficient of the reaction A' -f- B' = A -f- B, be K' ; the force of the reformation of A and B is equal to K'p'q'.
Page 190 - In this connection, it occurred to the authors that if a solution of a copper salt and one of potassium ferrocyanide are separated by a porous wall which is filled with water, and a current is passed from an electrode in the former to another in the latter solution the copper and the ferrocyanogen ions must meet in the interior of the wall and separate as copper ferrocyanide at all points of meeting, so that in the end there should be built up a continuous membrane well supported on either side by...
Page 3 - ... in the four compounds which are made up of potassium, chlorine, and oxygen, the quantity of oxygen varies, being twice as great in the second compound as in the first, three times as great in the third, and four times as great in the fourth. These facts, and others of the same kind, are...
