How is the angle of contact obtained in glass and water pairs?

Ans : Water spreads easily out on a clear glass surface, whereas Mercury prefers to form a droplet within the same surface. The angle of contact between the liquid and the glass determines the shape of a drop and the angle of contact is acute inside the event of a glass water interaction. As a result, water flows across the glass and an angle of contact is obtained.
