    Shoemaker Levy fragment G
    If you have ever wondered about the distribution function these observations about Fragment G helps to provide perspective about speed of the waves at the distance it had already covered.

    Nucleation is the process of forming particles from a purely gaseous precursor phase.

    There are two types of nucleation processes,

    1.homogenous nucleation
    2.heterogeneous nucleation.
    Nucleation occurs for different reasons. Important among them, is the supersaturation of a vapor. When a hot vapor in a gas is cooled down, its supersaturation ratio increases, and it becomes supersaturated. Therefore, it "precipitates out" into particles. This process is called nucleation.

    [edit] Coagulation When particles are present in an aerosol they collide with each other. During that they may undergo coalescence or aggregation. This process leads to a change in the aerosol size distribution function.

    [edit] Surface GrowthSurface growth is the process by which an aerosol particle grows with the accretion of monomers or individual molecules to an already existent particle.
