Match the 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:

CONCEPT:

Types of Solutions

• Solutions can exist in different phases, and they are classified based on the solute and solvent phases.
• Examples include:
  • Solid in solid (e.g., alloys)
  • Liquid in gas (e.g., humidity)
  • Solid in gas (e.g., smoke)
  • Liquid in solid (e.g., amalgams)

EXPLANATION:

• A. Humidity: Humidity refers to water vapor (liquid) dispersed in air (gas). This is an example of a liquid in gas solution. (A-II)
• B. Alloys: Alloys are homogeneous mixtures of metals or a metal and a non-metal in solid form. This is an example of a solid in solid solution. (B-I)
• C. Amalgams: Amalgams are alloys that consist of a metal (solid) dissolved in mercury (liquid). This is an example of a liquid in solid solution. (C-IV)
• D. Smoke: Smoke consists of tiny solid particles dispersed in a gas. This is an example of a solid in gas solution. (D-III)

Therefore, the correct option is 2) A-II, B-I, C-IV, D-III.
