- MCQ
Given below are two statements: \(Statement\) \(I\) : If a capillary tube is immersed first in cold water and then in hot water, the height of capillary rise will be smaller in hot water. \(Statement\) \(II\) : If a capillary tube is immersed first in cold water and then in hot water, the height of capillary rise will be smaller in cold water. In the light of the above statements, choose the most appropriate from the options given below
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) Statement\(I\) is true but Statement \(II\) is false
Step-by-step Solution
Detailed explanation
Surface tension will be less as temperature increases
\(\mathrm{h}=\frac{2 \mathrm{~T} \cos \theta}{\rho \mathrm{gr}}\)
Height of capillary rise will be smaller in hot water and larger in cold water.
