At a given pressure and temperature, the saturation pressure is the pressure at which a given liquid and its vapor can exist in equilibrium. The saturation pressure of a pure substance depends only on its temperature. As temperature increases, saturation pressure increases.
4 sie 2015 · How does saturated vapour pressure relate to vapour pressure? There are four terms you need to understand. pressure (i.e. the total pressure) vapor pressure; partial vapor pressure; saturated vapor pressure (identical with equilibrium vapor pressure.) Let's assume that water has a equilibrium vapor pressure of 18 torr at STP (760 toor, 20 ...
During the equilibrium state (i.e., at saturation) there is a balance between the rate of evaporation from the liquid and the rate of condensation from vapor. Liquid-water temperature controls the rate of evaporation, and humidity (water-vapor concentration in air) controls the rate of condensation.
Definition. Saturation pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its liquid phase at a given temperature. This concept is essential in understanding phase changes, as it indicates the point at which a substance can exist in both liquid and vapor forms without any net change in mass.
AN INTRODUCTION TO SATURATED VAPOUR PRESSURE. This page looks at how the equilibrium between a liquid (or a solid) and its vapour leads to the idea of a saturated vapour pressure. It also looks at how saturated vapour pressure varies with temperature, and the relationship between saturated vapour pressure and boiling point.
Ordinary evaporation is a surface phenomenon - some molecules have enough kinetic energy to escape. If the container is closed, an equilibrium is reached where an equal number of molecules return to the surface. The pressure of this equilibrium is called the saturation vapor pressure.
Definition. Saturation vapor pressure is the maximum pressure exerted by the vapor of a substance when it is in equilibrium with the liquid or solid phase of the same substance at a given temperature.
