Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is option 3. a-II, b-IV, c-I, d-III.
a-II: This matches paints, where pigment particles (solid) are dispersed in a volatile liquid (liquid) medium that evaporates after application, leaving the pigment embedded in the solid film.
b-IV: This matches jellies, where liquid fruit juices (liquid) are trapped within a rigid network of gelatin (solid) particles.
c-I: This matches soap lather, where air bubbles (gas) are dispersed within a soapy water solution (liquid) medium.
d-III: This matches pumice stone, which is a natural volcanic rock containing numerous air bubbles, making it a solid dispersed in gas (air).
