Homework Help: Nucleation radius

  1. Feb 22, 2007 #1
    for my thermodynamics class we have a question where we need to graph the evaporation and condensation rates as functions of g, the number of g-mers in our droplet of radius r. but condensation and evaporation are given in terms of r... is there an equation to relate r and g?

    i've looked online and found nothing, nor is it in our notes.

    hokay, so, we found that g*m=4(pi)r^3*rho.

    but now we realized that our E is just C* (the condensation rate at the critical radius r*). which can't be right because thats the same equation as C... we know they aren't equal throughout the entire graph because then every g would produce an r*.

    so whats E?
