Boiling Point Elevation and AgI Cloud-Seeding

Jennings, in 2020, proposed an equation for rise in superheat by adding electrolyte.  Expanding that equation (letting the limiting slope be the true slope) produces one which is quadratic in To, the limit of superheat.  The temperature of the solution is T and T - To is small and positive.  The surface tension be taken as constant because ΔT is so small, thus the quadratic is solved for To.  All of the variables are found and a simple formula, To = T - 3 ε T2 emerges using the binomial theorem where T is set at 288.2K, a typical temperature for a cloud producing rain.  The meaning of this simple formula is unclear, but it echoes boiling point elevation in that 3 ε T2 is roughly 2 millidegrees.  This relates to cloud-seeding, putting w2 at approximately 2 nanograms/cc, according to Standler and Vonnegut's estimate.  A 2021 paper by Jennings provides the rationale for linking this all to rainfall.
