Abstract: The classical homogenous nucleation theory was used to determine the efflorescence relative humidity (ERH) of aerosols with a wide size range at room temperature. For ammonium sulfate, the theoretical predictions compare favorably with the experimental data. With decreasing particle size, the ERH first decreases, reaches a minimum around 30%RH for particle diameter equal to about 30 nm, and then increases. Such a behavior is attributed to the Kelvin effect, which is important for small enough particles. Otherwise, the aerosol size is the dominant factor affecting the efflorescent behavior.
