Page 103 - ... the ratio of the ovendry weight of a sample to the weight of a volume of water equal to the volume of the sample at some specific moisture content, as green, air-dry, or ovendry.
Page 64 - It is measured by the product of the force by the force arm (the force arm is the perpendicular distance from the axis of rotation to the line of direction in which the force acts).
Page 146 - Evidently the same amount of heat lost by the water and calorimeter was gained by the ice and the water from the melted ice. Part of the heat was used in melting the ice; part in warming the water which resulted from melting the ice. It now remains to determine upon a unit of heat. We will adopt for our unit that amount of heat which will raise the temperature of 1 g. of water 1° C. We will call this a calorie. If one calorie will heat 1 g. of water 1° C., will one calorie be given out by 1 g....
Page 258 - It may also be defined as the sine of the angle of incidence divided by the sine of the angle of refraction, as light passes from air into the substance.
Page 308 - This latter expression is derived from the first. Chemically pure substances arranged in order of increasing resistance, from 20° C., for the same length and sectional area.
Page 197 - Variation of Distance between Plates. Keeping the porous cup in contact with the side of the jar, put the plates as far apart as possible (see Fig.
Page 64 - The moment of a force is the tendency of that force to produce rotation about an axis. It is measured by the product of the force...
