If a liquid does not wet glass, its angle of contact is
- A zero
- B acute
- C obtuse
- D right angle
Answer & Solution
Correct Answer
(C) obtuse
Step-by-step Solution
Detailed explanation
If a liquid does not wet glass, it means that the liquid-liquid interaction (cohesion) is more than liquid - solid interaction (adhesion). So, the angle of contact is obtuse.
