A model for the nonreactive uptake of gas molecules by liquids is described. The model uses the concept that the interface is a narrow region of a dense gaslike state within which nucleation is continually occurring. In this region, clusters that are formed in a critical size grow by condensation and merge with the nearby bulk liquid. The incoming gas molecule participates in this nucleation process. If this molecule becomes part of a critical-sized cluster, then it will be incorporated into
