2.0 Materials in the Gaseous State

For temperature-sensitive vapors (e.g., metal vapors generated at high temperatures, tritiated

water vapors), the amount of material volatilized can be estimated by the amount of heat

energy present and/or generated by the event. Similarly, condensation may also be

calculated by heat transfer at the surfaces or by homo- or heterogenous condensation in air.

The mass flux of vapors to a cool surface (diffusiophoresis) can be an effective mechanism to

sweep small diameter (i.e., submicron) particles from the air.
