The [[pressure]] exerted by the molecules of a given [[vapor]].</div><br/> <div class="paragraph">For a pure, confined vapor, it is that vapor's pressure on the walls of its containing vessel; for a vapor mixed with other vapors or gases, it is that vapor's contribution to the [[total pressure]] (i.e., its [[partial pressure]]). In meteorology, vapor pressure is used almost exclusively to denote the partial pressure of [[water vapor]] in the [[atmosphere]]. Care must be exercised in interpreting the term's meaning as used in other branches of science. <br/>''See'' [[saturation vapor pressure]], [[equilibrium vapor pressure]].</div><br/> </div>
