Which matching is incorrect?
Answer and explanation
Correct answer: Soda water: liquid in gas
Soda water is made when gaseous carbon dioxide dissolves in liquid water. Its correct classification is gas in liquid, not liquid in gas; therefore option C is the incorrect matching. Air is gas in gas, brass is solid in solid, and salt water is solid in liquid. Remembering that the solute is named first and the solvent second prevents the reversal in option C.
