for this question, Vapour pressure is right answer
Here’s a brief overview of the terms:
Vapor Pressure: The pressure exerted by the vapor of a liquid in equilibrium with its liquid phase at a given temperature. It is the pressure of the water vapor present above the liquid in a closed system.
Hydraulic Pressure: This refers to pressure in a fluid system, often related to hydraulic machinery or systems, not specifically to vapor.
Surface Tension: This is the force per unit length experienced at the surface of a liquid due to intermolecular forces, not related to vapor pressure.
Aqueous Tension: This term is less common but is sometimes used to refer to the tension or pressure related to water in specific contexts, but it is not a standard term for the partial pressure of water vapor.
Thus, the correct term for the partial pressure exerted by water vapor is vapor pressure.
