STANDARD Physics Angle of Contact MCQ Question
Which of the following statement is not true about angle of contact?
The value of angle of contact for pure water and glass is zero.
Angle of contact increases with increase in temperature of liquid.
If the angle of contact of a liquid and a solid surface is less than 90°, then the liquid spreads on the surface of solid.
Angle of contact depend upon the inclination of the solid surface to the liquid surface.
Correct Answer
Detailed Explanation
The angle of contact is a property of the liquid-solid pair and does not depend on the inclination of the solid surface.
