Viscosities and realted phase states of aerosol particles have become important knowlege in the aerosol community because of their effects on size distributions and heterogeneous reactions. However, information of the viscosities and phase states of atmospherically relavant aerosol particles as a function of relative humidities are still limited. Herein, we have quantified the relative humidity-dependent viscosities of aerosol particles consisting of sucrose mixed with ammonium sulfate for organic-to-inorganic dry mass ratios of 4:1, 1:1, and 1:4. From the viscosity results, we determined the phase states of liquid, semisolid, and solid of the particles. These results will be presented.
