Sida 177 - ... seen on considering some specific case. Ordinary ethyl alcohol and methyl ether differ greatly from each other — the first is a liquid whilst the second is a gas at ordinary temperatures — but possess the same molecular composition, the molecule in each case consisting of two atoms of carbon, six of hydrogen and one of oxygen.
Sida 231 - Avogadro's law states that equal volumes of all gases at the same temperature and pressure contain the same number of molecules...
Sida 151 - ABTU is the amount of heat required to raise the temperature of a pound of water one degree Fahrenheit.
Sida 81 - But if it is sufficiently compressed or cooled, it reaches a point where it begins to condense. It then no longer obeys the same laws as a gas...
Sida 21 - Thus molecular science sets us face to face with physiological theories. It forbids the physiologist from imagining that structural details of infinitely small dimensions can furnish an explanation of the infinite variety which exists in the properties and functions of the most minute organisms.
Sida 35 - A scale is marked upon this sheath, so that the height of the column above the surface of the mercury in the reservoir may be easily read.
Sida 141 - ... as fast as the latter gas. Absorption of Gases by Liquids.— Many gases are readily absorbed by water. Other liquids also possess this power in a greater or less degree. Water will for example, absorb its own volume of carbonic-acid gas...
Sida 20 - If we take a piece of any substance, say a bit of chalk, and divide it into small fragments, these still possess the properties of chalk. Divide any fragment again and again, and so long as a divided fragment is perceptible by aid of the microscope it still appears chalk.
