Solution

Vapor pressure of water:
Vapor pressure is the pressure that is caused by the evaporation of liquids.
Vapor pressure is affected by some common variables.
These variables are three in number that is intermolecular forces, surface area and temperature.
The vapor pressure of molecules varies under varying temperatures.
If water has a low vapor pressure it means water has high surface tension.
Some examples of vapor pressure are humid air, LPG cylinders, boiling of liquids, pressure cookers, etc.
According to Raoult's law $P_{s o l u t i o n} = X_{s o l v e n t} P_{s o l v e n t}$ , here $P_{s o l u t i o n}$ is the vapor pressure of the solution, $X_{s o l v e n t}$ is the mole fraction of the solvent, and $P_{s o l v e n t}$ is the vapor pressure of the pure solvent.
