Pressure Dependence of Liquid Vapor Pressure: An Improved Gibbs Prediction

A new model for the vapor phase of a pressurized liquid called "the cluster model: which is originally introduced in this work, along with an accurate equation of state for the liquid phase called the LIR, is used to derive an accurate equation for the vapor pressure of liquid as a function of external pressure. The chemical Potential of both phase have been found to be in good agreement wi...

A New Vapor Pressure Equation

The Wagner equation for prediction of vapor pressure has been modified in order to improve it accuracy. On the basis of this modifications, development of a new equation for prediction of vapor pressure is outlined. Examples of the use of the equation for obtaining vapor pressure for a total of 94 pure substance are given. The proposed equation combines simplicity and accuracy and performs as w...

Vapor pressure determination by thermogravimetry

A method for measuring the vapor pressures of a wide range of materials using a conventional thermobalance and standard sample holders is described. The equipment is calibrated using pure reference materials of known vapor pressure and exploiting the relationship between volatilization rate and vapor pressure based on the Langmuir equation for free evaporation. Enthalpies of vaporization and su...

The Vapor Pressure of Small Drops.

Gibbs did not consider the Kelvin equation for the vapor pressure of small drops for the obvious reason that it does not constitute chemical equilibrium. The Kelvin equation represents true equilibrium between vapor and a flat surface of liquid water, where the liquid is under a pressure greater than the vapor by any assigned value AP. For example, in a closed vessel in the presence of an inert...
