If a liquid does not wet glass, its angle of contact is

Options

  1. Azero
  2. Bacute
  3. Cobtuse
  4. Dright angle

Correct answer

C. obtuse

Step-by-step solution

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.
