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. WebAdhesion Force. 1. The force between the like molecules which hold the liquid together is called ‘cohesive force’. When the liquid is in contact with a solid, the molecules of these solid and liquid will experience an attractive force which is called ‘adhesive force’. 2.
