Match Column I with Column II
| Column I | Column II |
| i. Butter | a. dispersion of liquid in liquid |
| ii. Pumice stone | b. dispersion of solid in liquid |
| iii. Milk | c. Dispersion of gas in solid |
| iv. Paints | d. dispersion of liquid in solid |
Answer & explanation
Correct answer: option 1
The correct answer is option 1. i-d; ii-c; iii-a; iv-b.
| Column I | Column II |
| i. Butter | d. dispersion of liquid in solid |
| ii. Pumice stone | b. dispersion of solid in liquid |
| iii. Milk | a. dispersion of liquid in liquid |
| iv. Paints | c. Dispersion of gas in solid |
Let us break down each match with detailed explanations:
i. Butter: d. Dispersion of liquid in solid
Butter is essentially a water-in-fat emulsion where tiny droplets of water are dispersed in a continuous fat phase. This makes butter a solid with liquid dispersed in it.
ii. Pumice stone: b. Dispersion of gas in solid
Pumice stone is a type of volcanic rock that forms through rapid cooling and depressurization, trapping gas bubbles inside its solid structure. These gas pockets make the rock porous and light.
iii. Milk: a. Dispersion of liquid in liquid
Milk is an emulsion, which is a colloid where tiny droplets of fat are dispersed throughout a continuous phase of water. This type of system involves one liquid (fat) being dispersed in another liquid (water).
iv. Paints: c. Dispersion of solid in liquid
Paints consist of solid pigment particles that are finely dispersed in a liquid medium (such as water or oil). The liquid serves as the continuous phase in which the solid particles are distributed.
Thus, the correct matches are:1. i-d; ii-c; iii-a; iv-b
