Page 173 - What is meant by saying that the specific heat of water is 30 times as great as that of mercury? If a pound of boiling water is mixed with a pound of ice-cold mercury, what will be the temperature of the mixture ? 4.
Page 1 - In Fahrenheit's thermometer, the freezing point of water is marked 32°, and the boiling point 212° : in the Centigrade, the freezing point is 0°, and the boiling point 100°: in Reaumer's, the freezing point is 0°, and the boiling point 80°.
Page 109 - C. by the heat required to convert one gramme of water at 100° C. into steam at 100° C.
Page 108 - Latent heat is the quantity of heat which must be communicated to a body in a given state in order to convert it into another state without changing its temperature.
Page 56 - ... level in both branches, and at the zero of both scales. Thus we have, in the short branch, a quantity of air separated from the external air, and at the same pressure. Mercury is then poured into the long branch, so as to reduce the volume of this inclosed air by one-half; it will then be found that the difference of level of the mercury in the two branches is equal to the height of the barometer at the time of the experiment; the compressed air therefore exerts a pressure equal to that of two...
