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 (1) Statement I is false but Statement II is true (2) Both Statement I and Statement II are true (3) Both Statement I and Statement II are false (4) Statement I is true but Statement II is false

1. Statement I is false but Statement II is true
2. Both Statement I and Statement II are true
3. Both Statement I and Statement II are false
4. Statement I is true but Statement II is false

Correct answer: Statement I is true but Statement II is false

Solution

Statement I is correct because the height of capillary rise decreases in hot water due to lower surface tension compared to cold water. Statement II is incorrect as it suggests that the height of capillary rise would be smaller in cold water, which contradicts the established behavior of liquids in capillarity.
