greater than $90^{\circ}$

Vedclass · Answer

(D) The angle of contact $	heta$ determines the wetting behavior of a liquid on a solid surface.If $	heta If $	heta > 90^{\circ},$ the cohesive forces between liquid molecules are stronger than the adhesive forces between the liquid and the solid surface.Consequently,the liquid does not wet the solid surface (e.g.,mercury on glass).Therefore,the correct condition for a liquid not to wet a solid surface is that the angle of contact is greater than $90^{\circ}.$
