A two-dimensional liquid meniscus being attached to an inclined plate was chosen to investigate the physical mechanism of wetting observed macroscopically. In order to consider the macroscopic wetting behavior from a thermodynamic viewpoint, the Helmholtz free energy of the system was obtained theoretically. The system shows thermodynamic stability corresponding to a minimum of the free energy when the meniscus is attached to the solid surface at the contact angle. This result agrees with the popular view. In the case of a meniscus formed under a horizontal plate, however, there is no minimum of free energy, and the system is stable when the meniscus is attached to the solid surface at an angle between the advancing and receding contact angles.
