NEET Physics Surface Tension Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Capillary Rise | (i) Surface tension causes a pressure difference |
| (b) Hemispherical Bubble | (ii) Liquid will be lower in a capillary |
| (c) Concave Meniscus | (iii) Excess pressure is 2S/r |
| (d) Convex Meniscus | (iv) Liquid adheres to solid surface |
a-i, b-iii, c-iv, d-ii
a-ii, b-iv, c-i, d-iii
a-iii, b-i, c-ii, d-iv
a-iv, b-ii, c-iii, d-i
Correct Answer
Detailed Explanation
Capillary rise occurs due to surface tension creating a pressure difference (P_i - P_0 = 2S/r). A hemispherical bubble has excess pressure given by 2S/r, and a concave meniscus indicates adhesion between liquid and solid, while a convex meniscus shows liquid is lower in a capillary.
