Not illustrated. 1919 Excerpt: ...ovens. It is used in the manufacture of iron. Gas carbon is used for the carbon electrodes of arc lights. Vegetable matter has been transformed slowly into peat, lignite, bituminous coal and anthracite coal, and in some cases to graphite. Bituminous coals are distinguished as coking, non-coking and cannel coals. EXERCISES 1. The heat of combustion of a gram atom of diamonds is 94,310 small calories. That of a gram atom of amorphous carbon is 97,350 calories. Is the formation of diamonds from amorphous carbon exothermic or endothermic? Will the formation be favored by an increase or decrease of the temperature (see p. 121)? Will it be favored by pressure? 2. What volume of carbon dioxide will be formed by burning a gram of carbon? What volume of air will be required to furnish the oxygen for the combustion? 3. What volume of air will be required to burn a pound of carbon? What weight of air? 4. What volume and weight of air are required to burn a pound of hydrogen? 6. What volume and weight of air will be required to burn a pound of bituminous coal containing 73 per cent of carbon and 4.7 per cent of combustible hydrogen? 6. How many kilograms of water ought, theoretically, to be evaporated by the heat from burning a kilogram of coal which gives by its combustion 6500 calories per kilogram? How many pounds of water per pound of coal? How many pounds of water evaporated by a pound of coal is considered good boiler efficiency? CHAPTER XVIII HYDROCARBONS, GAS, FLAME Contrast of Carbon with Other Elements.--The elements of the halogen family each form only a single compound with hydrogen, of which hydrochloric acid, HCl, may be taken as typical. 0xygen forms two compounds, water, H20, and hydrogen peroxide, H202. Nitrogen forms four or five compounds but only am...
