In most basic chemistry courses a kinetic approach is used to explain the vapor pressure lowering for solutions with a non volatile solute. This approach has been considered intrinsically incorrectfor many years based on several objections. We consider that these objections are based on a ...
A general definition of vapor pressure is that it is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. From: Ecotoxicology Essentials, 2016
Learn vapor pressure definition and discover a few common examples which involve vapor pressure. Know and use formulas that involve the use of...
Volatile Organic Compounds (VOCsPredictThe objective of this investigation was to develop a vapor pressure (VP) acquisition system and methodologyfor performing temperature-dependent VPmeasurements and predicting the enthalpy of vaporization (ΔHvap) of volatile organic compounds, i.e. VOCs. H......

A substance with a high vapor pressure at normal temperatures is often referred to as volatile. The vapor pressure of any substance increases nonlinearly with temperature and the atmospheric boiling point of a liquid (also known as the normal boiling point) is the temperature at which the vapor ...
