The fraction of noncondensibles in a bubble controls the temperature driving force in the process of condensation and evaporation. It affects the vapor partial pressure, and consequently the apparent temperature of saturation. The present work deals with a bubble condensing in immiscible and in miscible liquids, and with the evaporation of a bubble in an immiscible liquid. The complete, exact expression of the dimensionless apparent saturation temperature is formulated, and all its terms are examined, including the variation of physical properties.
