NEET Physics Surface Tension Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Capillary rise | (i) Surface tension reduces angle of contact |
| (b) Wetting agents | (ii) Spherical shape of water drops |
| (c) Angle of contact | (iii) Height of liquid column |
| (d) Bubbles | (iv) Pressure difference due to curvature |
a-iii, b-i, c-iv, d-ii
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iii, d-iv
a-iv, b-ii, c-i, d-iii
Correct Answer
Detailed Explanation
Capillary rise relates to the height of the liquid column due to surface tension, which is given by equations connecting pressure difference and curvature. Wetting agents reduce the angle of contact, allowing better penetration of liquids. The shape of water drops is spherical because of surface tension, leading to pressure differences at the air-water interface which affects curvature.
