Is there any entropic gain when the surface of a liquid is minimised? Per example, molecules "enjoy" maximum entropy when they are at the interior. Is this valid?

Surface tension is related to the partial derivative of Helmholtz energy with respect to surface area of an interface, which means that minimizing the surface area also maximizes total entropy in a constant-volume process.

Thank you very much
