Determinação da entalpia de vaporização de líquidos pelo método do isoteniscópio de Smith e Menzies Determination of the enthalpy of vaporization of liquid compounds by the Smith Menzies (isoteniscope) method

<abstract language="eng">This article proposes an experimental procedure to determine the enthalpy (and entropy) of vaporization of organic liquid compounds, by the Smith-Menzies (isoteniscope) method. The values of vapor pressure at different temperatures were obtained and &#916...
