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 salt is added in salt solution then surface tension decreases.
In the light of the above statements, choose the most appropriate from the options given below
Text Solution
Verified by ExpertsThe correct answer is:
C
Height of capillary rise, 
As we know as temperature increases surface tension decreases so 
decreases.
Temperature ↑ surface tension ↓ → height ↓
