Vapor-liquid equilibrium — Vapor liquid equilibrium, abbreviated as VLE by some, is a condition where a liquid and its vapor (gas phase) are in equilibrium with each other, a condition or state where the rate of evaporation (liquid changing to vapor) equals the rate of… … Wikipedia
Vapor pressure — (also known as equilibrium vapor pressure or saturation vapor pressure ), is the pressure of a vapor in equilibrium with its non vapor phases. All liquids and solids have a tendency to evaporate to a gaseous form, and all gases have a tendency to … Wikipedia
Vapor pressure osmometry — is a technique to measure the number average molecular weight of a polymer. It is based upon Raoult s law that governs change in vapor pressure of a solution based on the mole fraction of the solute.The vapor pressure osmometer is composed of two … Wikipedia
Vapor — A vapor or vapour (see spelling differences) is a substance in the gas phase at a temperature lower than its critical temperature. [R.H.Petrucci, W.S.Harwood and F.G.Herring, General Chemistry , 8th edition (Prentice Hall 2002), p.486] This means … Wikipedia
vapor pressure lowering — the decrease of the vapor pressure of a solution below that of the pure solvent; the percentage change in vapor pressure is equal to the mole fraction of the solute (osmoles of solute per osmoles of solute plus solvent) and is proportional to the … Medical dictionary
vapor trails — A long trail of visible moisture left by an aircraft as it flies at high altitude through very cold air. The trails are formed by the condensation of water vapor in the exhaust gases leaving the engine. They appear at a slight distance behind… … Aviation dictionary
