Improved Experiment of Pure Liquid Steam Pressure Measurement

ZHOU Wei, DUAN Ping-he, LI Sen-lan ( Chemistry Department, Luoyang Normal College, Luoyang 471022; No. 26 Middle School of Luoyang, Luoyang 471022, China)  
The experiment equipments and methods of measuring pure liquid steam pressure. In the aspect of equipments, electronic barometer is replaced by Fortin barometer, electronic differential manometer replaces U-shaped manometer, Backman thermometer substitute 1/10 thermometer, accumulator tank is used to substitute accumulator bottle, and heating is also improved. In the operational aspect, boiling point definition indicates air in the closed balancing pipe is fully discharged; leveling with balancing pipe is adjusted, and system temperature is adjusted, as substituted means of adjusting system pressure. These improvements not only enable easy operations and save time, but attain accuracy. Take pure water as the object, when temperature is measured 30 ~80 ℃ , The linear dependent coefficients of straight line ln p - 1/T are all above 4 "9 ' s" ; the normal boiling point of water is 372. 4K, vaporization heat 42.93kJ/mol. Compared with documented values, the relative errors are respectively 0.03% and -0.07% .
