vapour pressure

n
(General Physics) physics the pressure exerted by a vapour. The saturated vapour pressure is that exerted by a vapour in equilibrium with its solid or liquid phase at a particular temperature

Robust detection of plastic explosives, which exhibit low vapour pressures, will still require residue detection even though bodies such as ICAO are encouraging the use of vapour `taggants'.
The contribution in question drew attention to the fact that evaporation from several phases in equilibrium enabled the formulation of systems evaporating with constant vapour pressure during extended times.
The general dependence of the vapour pressure on the emulsion composition is a necessary prerequisite in order to establish the evaporation path.
The vapour pressure is attained by substituting the value of [L.
V] available the evaporation path is calculated in a stepwise manner by reducing the water weight by a constant value, [DELTA]W, an appropriate approach, since the vapour pressure of water is constant during the processes analyzed.
