Given below are two statements : Statement-I: When a capillary tube is dipped into a liquid, the liquid neither rises nor falls in the capillary. The contact angle may be \(0^{\circ}\). Statement-II: The contact angle between a solid and a liquid is a property of the material of the solid and liquid as well : In the light of above statement, choose the correct answer from the options given below.
Pick an option to check your answer.
Answer & Solution
Correct Answer
(A) Statement-\(I\) is false but Statement-\(II\) is true.
Step-by-step Solution
Detailed explanation
Capillary rise
\(\mathrm{h}=\frac{2 \mathrm{~T} \cos \theta}{\rho \mathrm{gr}} \text {; }\)
If \(\theta=0^{\circ}\) then rise is non-zero
\(\therefore\) Statement- \(1\) is incorrect.
Option\((1)\) is correct
