"The angle of contact of mercury with glass is obtus, while the water with glass is acute." Why?

Text Solution

AI Generated Solution

To understand why the angle of contact of mercury with glass is obtuse while that of water with glass is acute, we can break down the explanation into clear steps: ### Step-by-Step Solution: 1. **Definition of Angle of Contact**: - The angle of contact (or wetting angle) is the angle formed between the tangent to the liquid surface at the point of contact and the solid surface (in this case, glass). 2. **Cohesive and Adhesive Forces**: ...
