Page 173 - It seems possible to account for all the phenomena of heat, if it be supposed that in solids the particles are in a constant state of vibratory motion, the particles of the hottest bodies moving with the greatest velocity...
Page 173 - ... and elastic fluids, besides the vibratory motion, which must be conceived greatest in the last, the particles have a motion round their own axes, with different velocities, the particles of elastic fluids moving with the greatest quickness ; and that in...
Page 326 - ... air than from the same conductor negatively charged, as may be seen in using the electrophorus. The greater facility with which positive electricity traverses the air may also be shown in the following manner : — Colour a card with vermilion ; unscrew the balls, a, 5, from the discharger. fig. 190, and place the points on opposite sides of the card, one about half an inch above the other ; discharge a large jar through the card. It will be perforated opposite the wire attached to the negative...
Page 444 - When an electric current passes round a ray of polarized light in a plane perpendicular to the ray, it causes the ray to revolve on its axis, as long as it is under the influence of the current, in the same direction as that in which the current is passing.
Page 50 - And why did the water rush into it?" Tom hesitated. "Was it not, think you, owing to the pressure of the atmosphere upon the surface of the water? When you raised the piston, the air above it was also. raised, and ultimately driven out by the force of the ascending piston; and since the air could not find any entrance from below as long as the point was under the water, the interior of the squirt would necessarily have remained quite...
Page 167 - Substances are said to be optically active when they produce rotation of the plane of polarisation of a ray of polarised light which passes through them. The rotation may be either to the right or to the left, according to the nature of the substance ; in the former case the substance is said to be dextro-rotatory ; in the latter, Izvo-rotatory.
Page 399 - ... although liquid at ordinary temperatures, cannot be decomposed so long as it is anhydrous, or free from water. To these laws may be added a sixth — viz. : 6. Those bodies only are electrolytes which are composed of a conductor and a non-conductor. The conductors accumulate on the platinode, the non-conductors on the zincode. For example, iodide of lead when melted conducts the current ; metallic lead, which is a conductor, accumulates at the platinode ; whilst iodine, which is a non-conductor...
Page 33 - This result gives the weight of a bulk of water equal to that of the specimen, and by dividing the weight of the specimen in air by this number, the specific gravity is obtained.
Page 379 - E r, the expression becomes ^ ; in order that the effect in the second circuit shall be rendered equal to this, it is evident that the added resistance must be multiplied by the same factor as that by which the electro-motive forces and...
Page 106 - ... lay the plate on the table with the edge, /, parallel to the window, the side to which the wax is attached being uppermost, and press the end of the wax against the crystal until it adheres ; then lift the plate with its attached crystal, and place it in the slit of the pin, x, with that side uppermost which rested on the table.
