A liquid will not wet the surface of solid if the angle of contact is which angle? -Do You Know?

A liquid will not wet the surface of solid if the angle of contact is which angle? -Do You Know?
by

1 Answer

Answer :

90o . A liquid does not wet the solid surface if the angle of contact is obtuse ie, greater than 90o . In this case cohesive forces will be greater than adhesive forces and so, the liquid does not wet the surface of solid.
