Why is water vapour studied separately while comparing the composition of dry air and moist air?
Answer and explanation
Correct answer: Because the amount of water vapour changes with place and time
Dry air is described mainly through relatively permanent gases, whereas water vapour is a variable component. Its amount changes with temperature, location, altitude, season and proximity to water bodies. Warm air can generally contain more vapour than cold air, and condensation can remove it from the air. Hence option B explains why it is treated separately; the other statements are scientifically false.
