"Web2.4.2 Work of Adhesion. The work of adhesion is defined as the reversible thermodynamic work required to separate the interface from the equilibrium state of two phases to a separation distance of infinity. Equation (2.10) shows the work of adhesion for a liquid–solid combination. This definition is attributed to the French scientist A. Dupre. " - Mechanical work vs thermodynamic work
