^a Each row corresponds to model calculations that address a combination of different solute effects on the droplet evaporation time: (I) the solute-induced droplet equilibrium size (II) the water vapor-pressure reduction in the presence of solutes (III) the solute-concentration dependence of evaporation cooling (IV) the evaporation-induced water concentration gradient inside the droplet, and (V) the solute-concentration dependence of the internal water diffusivity.
