Young-Laplace Capillary Pressure Calculator — Frequently Asked Questions
Q1 Why is pressure inside a tiny aerosol droplet so high? ▾
Because pressure jump is inversely proportional to radius R (ΔP = 2γ / R), as droplet radius approaches nanometer scales, the internal pressure skyrockets to dozens of atmospheres.
