Abstract NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. I. The enthalpy change upon vaporization of n-hexane was experimentally determined by calorimetric measurements at temperatures between 100[degrees] and 340[degrees]F. The results are presented in tabular and graphical form. Good agreement is indicated with the limited data available. II. The specific volumes of the liquid and dense phase of trans-2-butene were measured at pressures up to 5000 pounds per square inch in the temperature interval between 40[degrees] and 400[degrees]F. The latent heat of vaporization was determined from calorimetric measurements at temperatures between 100[degrees] and 250[degrees]F. The results are presented in graphical and tabular form together with comparisons with earlier published data. III. The enthalpy change upon vaporization, often referred to as the differential latent heat of vaporization, has been measured for the n-butane-n-decane system by calorimetric techniques. The measurements covered the complete composition range in the temperature interval between 100[degrees] and 340[degrees]F. The partial enthalpy change upon vaporization for n-butane was determined by applying a correction for the presence of small amounts of n-decane in the vapor. The partial internal energy change upon vaporization for n-butane was also computed. The results are presented in graphical and tabular form. A general thermodynamic analysis for withdrawal or addition of material to an isochoric vessel containing coexisting phases of a multi-component system is presented
