1. Partial Pressure

   Linked via "cryogenic environments"

   The saturation vapor pressure ($P{\text{sat}}$) of a substance is the maximum partial pressure that its vapor can achieve at a given temperature when the system is at equilibrium with its condensed phase. If the actual partial pressure of that substance in the surrounding atmosphere exceeds $P{\text{sat}}$, condensation (or deposition) must occur to re-establish equilibrium [2].
