Match List-I with List-II.
Column I
- A. Humidity
- B. Alloys
- C. Amalgams
- D. Smoke
Column II
- I. Solid in solid
- II. Liquid in gas
- III. Solid in gas
- IV. Liquid in solid
Correct answer: A → II, B → I, C → IV, D → III
Explanation
Humidity: Liquid in gas; Alloys: Solid in solid; Amalgams: Liquid in solid; Smoke: Solid in gas.
Detailed Solution
Classification of solution types: 1. Humidity represents water vapour dispersed in air (liquid in gas, II). 2. Alloys are homogeneous solid solutions of metals (solid in solid, I). 3. Amalgams are liquid mercury dissolved in a solid metal (liquid in solid, IV). 4. Smoke consists of solid carbon/dust particles dispersed in air (solid in gas, III). Therefore, the correct matching is A-II, B-I, C-IV, D-III.
