To quickly assess the difficulty of the text, read a short excerpt:
The temperature 30'9°C. [87*6°F.] is called the critical temperature of carbon dioxide. There is a critical temperature for each gas, that is, a temperature above which the gas cannot be caused to become liquid by compressing it. The critical temperatures of dif- ferent gases are very different ; for instance, the critical temperature of gaseous alcohol is about 240°C. [464°F.], and that of hydrogen is about minus 234°C. [minus 389°F.]. This statement means that gaseous alcohol can be liquefied... by pressure provided the temperature is lower than 464°F.; but that if it is wished to liquefy hydrogen by compressing it, the gas must be cooled to at least 389° below the zero of Fahrenheit's scale. Liquid carbon dioxide is a marketable com- modity ; it is sold in strong steel bottles which generally contain about 15 lbs. of the liquid = about 12 cub. feet of the gas at the ordinary temperature of the air. Liquid carbon dioxide is used for extinguishing fires, for propelling torpedoes, for obtaining cold by allowing the liquid to evaporate, for aerating water, and for other purposes.
