精密绝热量热计的建立及乙二醇水溶液二元体系热容的测定
摘要
A precision adiabatic calorimeter for determining heat capacities of liquids at temperature ranging from -80℃ to 126℃ has been developed. Adiabatic control of the heat shield is carried out automatically. The temperature of the calorimeter sample vessel is measured-by means of a standard platinum thermometer.The reliability of this equipment may be justified by measuring the heat capacity of n-heptane which is used as a standard recommended by the Calorimetry Conference. The results obtained are found to be in accord with the NBS data with a deviation within 0.5％.With this device the heat capacities of 10 aqueous solutions of ethylene glycol at different concentrations have been measured.
