This question has Statement-1 and Statement- 2 . Of the four choices given after the Statements, choose the one that best describes the two Statetnents. Statement-1: A capillary is dipped in a liquid and liquid rises to a height in it. As the temperature of the liquid is raised, the height increases (if the density of the liquid and the angle of contact remain the same). Statement-2: Surface tension of a liquid decreases with the rise in its temperature.

Options:

Answer:
B
Solution:

Surface tension of a liquid decreases with the rise in temperture. At the boiling point of liquid, surface tension is zero. Capillary rise As surface tension decreases with rise in temperature hence capillary rise also decreases.
