24 Απρ 2021 · Learn what vapor pressure is and how to calculate it using Raoult's law and the Clausius-Clapeyron equation. Find vapor pressure values for common liquids and examples of volatile and nonvolatile substances.
Equation \(\ref{Eq1}\), called the Clausius–Clapeyron Equation, can be used to calculate the \(ΔH_{vap}\) of a liquid from its measured vapor pressure at two or more temperatures.
Learn what vapour pressure is, how it depends on temperature and nature of the liquid, and how it relates to Raoult's law and boiling point. Find the formula for vapour pressure of pure liquids and solutions, and watch videos and FAQs on the topic.
Vapor pressure [a] or equilibrium vapor pressure 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. The equilibrium vapor pressure is an indication of a liquid's thermodynamic tendency to evaporate.
The pressure exerted by the vapor in equilibrium with a liquid in a closed container at a given temperature is called the liquid’s vapor pressure (or equilibrium vapor pressure).
With this vapor pressure calculator, we present to you two vapor pressure equations! Have you found yourself wondering: what is vapor pressure? How does a liquid change into a gas due to a change in pressure and temperature?
