    Apr 24, 2021 · Vapor pressure (or vapour pressure) is the equilibrium pressure of a vapor above its liquid or solid state in a closed container. In this type of closed system, some molecules of a liquid or solid have enough kinetic energy to escape at the surface and enter the vapor (gas) phase.

    Mar 13, 2023 · Vapor pressure is the pressure inside a closed container when a liquid is in equilibrium with its own gas phase so the rate of evaporation is equal to the rate of condensation. When a non-volatile solute is dissolved in a volatile solvent, the vapor pressure of the solvent is reduced.
