1 Vapor Pressure of a Pure Liquid Objective Measure the vapor pressure of a liquid as a function of temperature and to use this information to determine the heat of vaporization and the compressibility factor. Theory Consider a system composed of a pure liquid that is in coexistence with its ...
The Clausius-Clapeyron relation describes the water liquid-vapor equilibrium as a function of pressure and temperature. Global atmospheric water vapor should increase by about 6%/°C to 7%/°C and satellite data over the oceans agree with this estimate (Santer et al., 2007); increases in water...
For water, the SPC- and TIP4P models give superior results for the vapor pressure when compared to the SPC/E model. The vapor–liquid equilibrium of the binary mixture, carbon dioxide–water, was predicted using the SPC- as well as the TIP4P model for water and the EPM2 model for carbon...
Besides the normal states of surface liquid, vapor, or ice, much water exists locked in rock hundreds of miles deep in Earth's mantle. 除了表面覆盖的江湖海水,水蒸气、冰,大部分水可能被锁在地球的地幔深处。 article.yeeyan.org 3. in the tank because of plugged or pinched lines or from a ...

Vapor–liquid equilibrium of the (water + ethanol + glycerol) system: Experimental and modelling data at normal pressure In this work, vapor-liquid equilibrium data of the ethanol-water-glycerol system were measured in an Othmer-type ebulliometer at normal pressure. The choic... WLR Souza,CS ...
Vapor−liquid equilibria of water + methanol, in the presence of binary salts of sodium chloride, potassium chloride, and sodium bromide, were studied at 298.15 K. The single salt−mixed solvent systems were also reported. A modified Othmer still was employed. The estimated accuracy of the ...
This work presents the first systematic study on the influence of water on the solubility of carbon dioxide in hygroscopic ILs. It was observed that the presence of water reduces the absolute solubility of CO2. However, at fixed ratios of CO2/IL, the bubble point pressure remains almost ...
