Surface Tension
PHXI10:MECHANICAL PROPERTIES OF FLUIDS

361156 This question has statement- 1 and statement-2. Of the four choices given after the statements, choose the one that best describes the two statements.
Statement-1: A capillary is dipped in a liquid and liquid rises to a height \(h\) in it. As temperature of the liquid is raised, the height \(h\) 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.

1 Statement-1 is ture, Statement-2 is true; Statement-2 is not the correct explanation for Statement-1.
2 Statement-1, is false, Statement-2 is true
3 Statement-1 is true, Statement-2 is false.
4 Statement-1 is ture, Statement-2 is true; Statement- 2 is the correct explanation for Statement-1.

361157 Water rises to a height \(h\) is a capillary at the surface of earth. On the surface of the moon the height of water column in the same capillary is
\(\left(g_{m}=\dfrac{g_{e}}{6}\right)\)

1 Zero
2 \(6\;h\)
3 \(\dfrac{1}{6} h\)
4 \(h\)

361158 Wax is coated on the inner wall of a capillary tube and the tube is then dipped in water. Then, compared to the unwaxed capillary, the angle of contact \(\theta\) and the height \(h\) upto which water rises change. These changes are:

1 \(\theta\) increases and \(h\) also increases
2 \(\theta\) decreases and \(h\) also decreases
3 \(\theta\) increaes and \(h\) decreases
4 \(\theta\) decreases and \(h\) increases
PHXI10:MECHANICAL PROPERTIES OF FLUIDS

361159 The rise of liquid into capillary tube is \(h_{1}\). If the apparatus is taken in a lift moving up with acceleration, the height is \(h_{2}\), then

1 \({h_1} = {h_2}\)
2 \(h_{1}>h_{2}\)
3 \(h_{2}>h_{1}\)
4 \(h_{2}=0\)
