46. lappuse - Every particle of matter, in the universe, attracts every other particle with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
117. lappuse - ... hence it follows, that the pressure of the atmosphere is equal to that of a column of mercury, the height of which is thirty inches.
750. lappuse - Towards the end of the last century, and at the beginning of the present...
852. lappuse - 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.
75. lappuse - The pressure per unit of area exerted anywhere upon a mass of liquid is transmitted undiminished in all directions, and acts with the same force upon all surfaces, in a direction at right angles to those surfaces.
847. lappuse - ... laterally. The form and relative position when seen in the distance frequently give the idea of shoals of fish. The tendency of cumulostratus is to spread, settle down into the nimbus, and finally fall as rain. The height of clouds varies greatly...
362. lappuse - By a unit of heat is meant the quantity of heat necessary to raise the temperature of one kilogramme of water one degree centigrade, or more accurately from 0° to 1°.
131. lappuse - Law. — The temperature remaining the same, the volume of a given quantity of gas varies inversely as the pressure.
406. lappuse - Heat is a very brisk agitation of the insensible parts of the object, which produces in us that sensation from whence we denominate the object hot ; so what in our sensation, is heat, in the object is nothing but motion.
