Question

Explain Laplases molecular theory?? (Physics Chpater 3)
​

Answer 1

Answer:

A molecular theory of surface tension is developed for a liquid–gas interface of a one component system. The Helmholtz free energy, the quantity minimized in the van der Waals approach, is obtained here from a rigorous expansion in powers of derivatives of density ρ and is minimized by the calculus of variations.
