Understanding +4 | -1

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

View answer and explanation

Correct option: D

Statement I is true but Statement II is false

Statement I is true and Statement II is false because the height of capillary rise is inversely proportional to the surface tension, which decreases with increasing temperature.
