JEE PHYSICS MCQ: MECHANICAL PROPERTIES OF FLUIDS

1 Medium

1 of 1

Analyzing +4 | -1

This question has statement -I and statement-II of the four choices given after the statements. Choose the one that best describes the two statements.
Statement-I: A capillary tube is dipped in a liquid rises to a height

h

in it. As the temperature of the liquid is raised, the height

h

decreases (if the density of the liquid and the angle of contact remain the same)
Statement-II: Surface tension of a liquid decreases with the rise in its temperature.

View answer and explanation

Correct option: A

Statement I and statement II are true and statement II is correct explanation of statement I

Option A is correct because the height a liquid rises in a capillary tube decreases with increasing temperature due to the decrease in surface tension, as stated in Statement II, which explains Statement I.
