Which option gives the correct order of gaseous, liquid, and solid solutions?
Answer and explanation
Correct answer: Air, salt in water, brass
The first example must be gaseous: air is a homogeneous mixture of gases and is classified as gas in gas. The second must be liquid: salt dissolved in water has liquid water as its solvent. The third must be solid: brass is a solid alloy and is classified as solid in solid. Therefore the sequence in option A exactly matches gaseous, liquid, and solid solutions.
