Water sticks to glass whereas mercury does not. Explain.

Text Solution

Verified by Experts

The angle of contact between water and glass is whereas that between mercury and glass is obtuse. Hence cohesive force between molecules of mercury is more than the adhesive force between molecules of mercury and glass. Apparontly mercury does not wet glass whereas water does.
