Physics-Surface Tension

NEET Physics Surface Tension Match the Following Question

Type: Match the Following-match the column-Hard-Class 11

Match Column-I with Column-II.

Column-I Column-II (a) Surface tension of water (i) 7.30 × 10 -2 Nm -1 (b) Effect of temperature (ii) Decreases with increase in temperature (c) Shape of liquid drop (iii) Always spherical under no external forces (d) Excess pressure in bubbles (iv) Given by 2S/r

Choose the correct matching:

A

a-i, b-ii, c-iii, d-iv

B

a-ii, b-i, c-iv, d-iii

C

a-iv, b-iii, c-ii, d-i

D

a-iii, b-iv, c-i, d-ii

Correct Answer

Option A

Detailed Explanation

The surface tension of water is given as 7.30 × 10 -2 Nm -1. Surface tension decreases with an increase in temperature, and a drop of liquid under no external forces is always spherical. The excess pressure in bubbles is calculated using the formula 2S/r.
