| Inhoud: |
This analysis demonstrates that, at least in some cases, continuum mechanics can be successfully applied in problems involving very thin films, so long as proper recognition is given to long-range intermolecular forces and to the finite size of molecules. In this particular case, the integral mechanical energy balance is used to analyze a simple thought experiment in which a thin liquid film is slowly stretched. The result is an expression for surface tension as a function of the Hamaker constant describing liquid-liquid, long-range intermolecular forces, the molecular weight, and the liquid density, which is in good agreement with previous experimental measurements for n-alkanes. |
