Page 32 - Now in firing a ball against a target the projectile, after collision, is often found hissing hot. Mr. Fairbairn informs me that in the experiments at Shoeburyness it is a common thing to see a flash of light, even in broad day, when the ball strikes the target. And if I examine my lead weight after...
Page 27 - But we have learned that two volumes of hydrogen unite with one of oxygen to form water...
Page 68 - It states that at any given temperature, the volume of a given mass of gas varies inversely as the pressure to which it is subjected.
Page 129 - One volume of hydrogen unites with one volume of chlorine to produce two volumes of hydrogen chloride.
Page 95 - Thus, one volume of hydrogen combines with one volume of chlorine to form two volumes of hydrochloric acid gas...
Page 88 - ... studying nitrogen we ask if it also will combine with hydrogen, and if it does, what the nature of the resulting compound is. Direct Union of Nitrogen and Hydrogen Difficult. The chemically indifferent nature of nitrogen becomes apparent when we make the attempt to bring about its union with hydrogen. If an electric spark is passed through a mixture of hydrogen and nitrogen no explosion takes place, and even if the operation is continued for some time the elements will be found to have united...

This point is called the dew point ; and, as the exact amount of water vapor which can be contained in a given volume of the atmosphere at any definite temperature is known, the discovery of the dew point affords a ready means of ascertaining the amount of moisture in the air. The ratio between the tension of the water...
