Calculate the exact vapor pressure of liquids at any given temperature using the Antoine Equation.
Watch how heating a liquid increases its vapor pressure inside a closed container.
Select substance and temperature to find the equilibrium vapor pressure.
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. It indicates a liquid's evaporation rate.
As temperature increases, more molecules have enough kinetic energy to escape the liquid surface, causing vapor pressure to increase non-linearly (exponentially).
The liquid boils! Boiling is defined as the point where the internal vapor pressure of the liquid equals the surrounding ambient pressure, allowing vapor bubbles to form within the bulk liquid.
