Angle of Contact & Capillarity
Given below are two statements:
Statement I: The contact angle between a solid and a liquid is a property of the material of the solid and liquid as well.
Statement II: The rise of a liquid in a capillary tube does not depend on the inner radius of the tube. In the light of the above statements, choose the correct answer from the options given below:
Show answer and solution
Answer: (d)
- Statement I: contact angle depends on both the solid and the liquid. True.
- Statement II: , so ; it does depend on radius. False.
- So the answer is (d) Statement I is true but Statement II is false.
