Water vapour mixing with air is closer to which state arrangement?
Answer and explanation
Correct answer: Gas in gas
Water vapour is water in the gaseous state, and air is also a gaseous mixture. When water vapour spreads uniformly through air, the arrangement is gas in gas, so option A is correct. The other options involve a solid or liquid as one component. Fog is different because it contains liquid droplets dispersed in air, not water vapour mixed molecule by molecule.
