Page 50 - 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.
Page 124 - ... 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.
Page 783 - Towards the end of the last century, and at the beginning of the present...
Page 94 - The weight of the body is either totally or partially overcome by its buoyancy, by which it is concluded that a body immersed in a liquid loses a part of its weight equal to the weight of the displaced liquid.
Page 902 - 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.
Page 383 - 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°.

Page 184 - The distance at which sounds can be heard depends on their intensity. The report of a volcano at St. Vincent was heard at Demerara, 300 miles off, and the firing at Waterloo was heard at Dover.
Page 140 - C, makes two atmospheres. Accordingly, by doubling the pressure, the volume of the gas has been diminished to one-half. If mercury be poured into the longer branch until the volume of the air is reduced to one-third its original volume, it will be found that the distance between the level of the two tubes is equal to two barometric columns.
