Which solution exists in the gaseous state at room temperature?
Answer and explanation
Correct answer: Air
Air is a homogeneous mixture of gases such as nitrogen, oxygen, argon and carbon dioxide, so it is treated as a gaseous solution. At room temperature, its solvent or continuous medium is gaseous. Salt water and sugar water have liquid water as the solvent, while brass is a solid alloy; therefore, they are not gaseous solutions.
