"WebJul 17, 2024 · Dry air consists mostly of nitrogen and oxygen molecules, which weigh more than water molecules. This means that when a given volume of air is made more moist by adding water molecules, heavier molecules are replaced with lighter molecules. Therefore, moist air is lighter than dry air if both are at the same temperature and pressure. " - Is humid air more or less dense than dry air

Is humid air more or less dense than dry air

WebJan 25, 2024 · The main reason cold air is denser than hot air is due to the fact that hot air has more water vapor. This is because the molecules of hot water have more space between them, and therefore weigh less. In other words, cold air is more dense than warm air. However, this doesn’t mean that hotter and drier are necessarily better.
