Q.82) Match List - I with List - II
List-I (Example) | List-II (Type of Solution) |
A. Humidity | I. Solid in solid |
B. Alloys | II. Liquid in gas |
C. Amalgams | III. Solid in gas |
D. Smoke | IV. Liquid in solid |
Choose the correct answer from the options given below:
A) A-III, B-II, C-I, D-IV
B) A-II, B-IV, C-I, D-III
C) A-II, B-I, C-IV, D-III
D) A-III, B-I, C-IV, D-II
Q.82) A. Humidity
Humidity = water vapor in air
- Water is liquid, air is gas
Type: Liquid in gas $\rightarrow$ II
B. Alloys
Example: Brass ( Zn in Cu ), Steel ( C in Fe )
- Metal solid dissolved in another solid
Type: Solid in solid $\rightarrow$ I
C. Amalgams
Metal + Mercury
- Mercury is a liquid, other metals are usually solid
Type: Liquid in solid $\rightarrow$ IV
D. Smoke
Solid particles (e.g., soot) in air
- Solid in gas
Type: Solid in gas $\rightarrow$ III
Hence, the correct answer is option (3).
