By John

Concepts and reason
Vapor pressure is the pressure exerted by the vapor in equilibrium with its condensed phase (liquid or solid) in a closed system at the given temperature.

Fundamentals
The relationship between temperature and pressure is expressed with the help of the Clausius–Clapeyron equation:
