SUMMARY
Vapour pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases within a closed system. This pressure applies equally to both the container and the liquid surface, as established by Pascal's law, which states that static pressure in fluids is uniform in all directions. The pressure of saturated vapor, which varies with temperature and the curvature of the liquid surface, is a critical value found in thermodynamic tables. Additionally, atmospheric pressure variations, such as those experienced at higher altitudes, affect the overall pressure exerted on the container, as described by the barometric formula.
