Σελίδα 48 - These quantities of heat, expressed relatively to the quantity of heat required to raise the temperature of an equal weight of water from 0° to 1° C., are called the specific heats of the various substances : thus the experiments just described show that the specific heat of olive oil is...
Σελίδα 157 - Its preparation, by the action of a mixture of nitric and sulphuric acids upon glycerine, requires the greatest care, in consequence of the force with which it is liable to explode.
Σελίδα 121 - Boyle's law states that, at a constant temperature, the volume of a gas is inversely proportional to the pressure: 1 1 VOL — P or V = constant x— or PV = constant.
Σελίδα 48 - ... evaporation no longer takes place quietly on the surface. The bubbles of saturated vapor expand against the pressure of the surrounding atmosphere and that of the small layer of liquid above them as they rise to the surface, while at the same time the liquid rapidly evaporates into the bubble from all sides. The boiling point of a substance is the temperature at which the vapor tension of the substance equals the gas pressure upon the liquid, no matter to what this pressure may be due. The "normal"...
Σελίδα 59 - In dilute solutions the rise of the boiling point and the lowering of the freezing point are proportional to the amount of dissolved substance in a given volume.
