The partial pressure exerted by the water vapors is called?
Correct answer: B. Aqueous tension
- A. Tension
- B. Aqueous tension
- C. Aqueous pressure
- D. All of these
Explanation
Option A: Tension is a force along the length of a medium, especially a force carried by a flexible medium, such as a rope or cable. Tension can be defined as an action-reaction pair of forces acting at each end of the said elements. Option: B Aqueous tension is the pressure exerted by the saturated water vapor. All gases are generally collected over the water as they are moist. ... Hence, the Pressure of dry gas = Pressure of moist gas - aqueous tension. Option C: Aqueous pressure refers to the partial pressure of water vapor above a solution. When a solution is placed in a closed container, water molecules from the solution can evaporate and contribute to the partial pressure of water vapor in the container. The aqueous pressure is the pressure exerted by the water vapor in the container, and it is dependent on the concentration of water in the solution and the temperature of the system.

About Evaporation, Boiling Point and Vapour Pressure
Evaporation is the escape of higher-energy molecules from a liquid surface, while vapour pressure is the pressure exerted by vapour in equilibrium with that liquid. The topic distinguishes evaporation from boiling and relates both to temperature, intermolecular forces, surface area, atmospheric pressure and the boiling point.
