Kelvin framework: ln(p/p_sat) = 2γ·V_m/(r·R·T) (curvature → vapor-pressure shift)

The Kelvin (Thomson 1871) equation — the thermodynamic consequence of Young-Laplace curvature pressure on a droplet's or meniscus's vapor pressure. Derivation: combine the Young-Laplace overpressure ΔP = 2γ/r (for a spherical droplet of…
