28 ページ - It is better, on this account, in graduating the bottle, to make two scratches, as represented in the figure, one at the top and the other at the bottom of the curve: this prevents any future mistake.
72 ページ - ... trustworthy results are obtained by measuring the quantity of heat generated by the friction between solids and liquids. It was for a long time believed that no heat was evolved by the friction of liquids and gases ; but in 1842 Meyer showed that the temperature of water may be raised 22° or 23° F.
42 ページ - C == 140° F. The rule then will be the following : — To convert Centigrade degrees into Fahrenheit degrees, multiply by 9, divide the product by 5, and add 32; to convert Fahrenheit degrees into Centigrade degrees, subtract 32, multiply by 5, and divide by 9. The reduction of negative degrees, or those below zero of one scale into those of another scale, is effected in the same way.
73 ページ - J, and the pulleys were connected by fine twine with a wooden roller r, which, by means of a pin, could be easily attached to or removed from the friction apparatus. The mode of experimenting was as follows: — The temperature of the frictional apparatus having been ascertained, and the weights wound up, the roller was fixed to the axis, and the precise height of the weights ascertained ; the roller was then set at liberty, and allowed to revolve till the weights touched the floor. The roller was...
132 ページ - I have spoken of it, are similar to those of the law of molecular diffusion, but it is important to observe that the phenomena of effusion and diffusion are distinct and essentially different in their nature. The effusion movement affects masses of gas, the diffusion movement affects molecules ; and a gas is usually carried by the former kind of impulse with a velocity many thousand times greater than by the latter.
629 ページ - This is secured by its being washed in a stream of water for several weeks. Subsequently a weak solution of potash may be used, but this is not essential. The prolonged continuance of these processes...
74 ページ - That the quantity of heat produced by the friction of bodies, whether solid or liquid, is always proportional to the force expended. 2. That the quantity of heat capable of increasing the temperature of 1 Ib. of water (weighed in vacua, and bet-ween 55° and 60°...
254 ページ - In all experiments in which water was decomposed, both acid and alkali were liberated at the electrodes, even though distilled water was employed ; and hence it was believed for some time that the voltaic current had some mysterious power of generating acid and alkaline matter. The true source of these compounds was, however, traced by Davy,* who showed that they proceeded from impurities either in the water itself, or in the vessels which contained it, or in the surrounding atmosphere.
75 ページ - The immediate cause of the phenomena of heat then is motion, and the laws of its communication are precisely the same, as the laws of the communication of motion.
63 ページ - Fah.), when the alcohol occupies just half the volume of the tube ; if the tube is more than half filled with alcohol, it bursts when heated. A glass tube one-third filled with water becomes opaque when heated, and bursts after a few seconds. If this chemical action of the water on the glass be diminished by the addition of a little carbonate of soda, the transparency of the glass will be much less impaired ; and if the space occupied by the water be ^ of the whole tube, the liquid will be converted...
