A liquid does not wet the solid surface if angle of contact is (a) zero (b) equal to 45° (c) equal to 60° (d) greater than 90°

Answer: (d). A liquid wets a surface when θ 90° (e.g. mercury on glass). So the answer is (d) greater than 90°.

Angle of Contact & Capillarity

A liquid does not wet the solid surface if angle of contact is

Show answer and solution

Answer: (d)

A liquid wets a surface when $\theta < 90^\circ$ and does not wet it when $\theta > 90^\circ$ (e.g. mercury on glass).
So the answer is (d) greater than $90^\circ$ .
