Is moist air heavier than dry air? Explain.

Text Solution

Verified by Experts

Dry air is heavier than moist air because dry air contains mainly `N_(2) and O_(2)` whose vapour densities are higher than the vapour density of `H_(2)O` present in moist air. [vapour densities of `N_(2),O_(2)` and `H_(2)O` are 14,16 and 9 respectively].
