Equilibrium or vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium. The manometer can be used to measure the liquid's vapor pressure.
Equilibrium Vapor Pressure
Equilibrium or vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a particular temperature in a closed system is defined as vapor pressure.
The equilibrium vapor pressure indicates the rate of evaporation of a liquid.
The manometer can be used to measure the liquid's vapor pressure. It is accomplished by injecting a small amount of liquid into a closed flask linked to a manometer.
