Question

What is vapour pressure of liquids? How the vapour pressure of a liquid is related to its boiling point?

Answer 1

vapor pressure is pressure exerted by vapours of liquid at equilibrium take example of h2O water stored in a bottle, after a certain time the rate of vapour formation and condensations of vapour becomes equal at that stage the pressure on walls of bottle will be called as vapour pressure

Answer 2

It has no component perpendicular to the horizontal surface. As a result, there is no pressure difference between the liquid side and the vapour side. ... Thus, there is always an excess of pressure on the concave side of a curved liquid surface over the pressure on its convex side due to surface tension.
