The Antoine equation [3][4] is a pragmatic mathematical expression of the relation between the vapor pressure and the temperature of pure liquid or solid substances.
Vapor pressure can be calculated using different formulas depending on the situation. It depends on temperature and the nature of the liquid. Two important equations help describe vapor pressure:.
Apr 24, 2021 · There are several vapor pressure formulas, but two common ones are Raoult’s law and the Clausius-Clapeyron equation.
Jan 30, 2023 · The change in vapor pressure of a pure substance as temperature changes can be described using the equation known as the Clausius-Clapeyron Equation: (1) l n P 2 P 1 = Δ H v a p.
Definition: Vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. Purpose: This calculator helps determine the vapor.
The vapor pressure calculator helps you learn about phase transition, latent heat, the Clausius-Clapeyron equation and other parts of thermodynamics and chemistry.
Jan 13, 2026 · Determine vapor pressure for pure liquids and mixtures. Explore thermodynamic and empirical calculation methods with practical examples.
Sep 23, 2024 · To calculate vapor pressure, use the Clausius-Clapeyron equation, which includes the variables for the enthalpy of the liquid, the real gas constant, the starting and final temperatures, and.
Equation \ref {2} is known as the Clausius-Clapeyron Equation and allows us to estimate the vapor pressure at another temperature, if the vapor pressure is known at some temperature, and if the.
Feb 1, 2026 · Vapor pressure is a property of a liquid based on the strength of its intermolecular forces. A liquid with weak intermolecular forces evaporates more easily and has a high vapor pressure. A.
