The physical process of converting a material from a gaseous or vapour phase to a
liquid or solid phase; this commonly results when the temperature is lowered and/or
the vapour pressure of the material is increased. The tendency exists for condensation
to occur when the
partial pressure of a given component of a gaseous mixture at a given temperature exceeds the vapour
pressure of the liquid or solid form of that component at the given temperature.
