Question

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:

TestHub · Accepted Answer

Statement I is correct as we know contact angle depends on cohesine and adhesive forces. Statement II is incorrect because height of liquid is given by h == ρ g r 2 T c o s θ C ​ ​ where r is radius of Tube (assuming length of capillary is sufficient).
