A practical method of estimating thermal expansion coefficients of liquids

Abstract

A partir de las ecuaciones de Gladstone-Dale, Lorentz- Lorenz y Eykman se obtienen otras relaciones que permiten evaluar los coeficientes de expansion termica de liquidos en funcion de la temperatura. Los coeficientes de expansion termica de los alcoholes puros, obtenidos mediante las relaciones ronseguidas, se aproximan bastante a los experimentales confirmando la validez de las ecuaciones en un rango de temperaturas de 20-45 ° C.

From Gladstone-Dale, Lorentz-Lorenz and Eykman equations we have derived others relationships which permit to obtain the thermal expansion coefficients of Hquids as a function of temperature. Thermal expansion coefficients of the pure alcohols predicted through empirical relations were found to be in fairly good agreement with the experimental data and to have validity over the temperature range 20-45° C.
