What is the difference between dry air and atmospheric air?
Expert Solution & Answer
To determine
The difference between dry air and atmospheric air.
Explanation of Solution
The presence of humidity is the biggest difference between dry air and atmospheric air. Humidity is present in atmospheric air whereas there is no humidity in dry air.
Dry air is stated as air that contains zero water vapor and has a low relative humidity. Atmospheric air is called as the air which is usual under atmospheric conditions and is unlike for changed locations and dependent on wind patterns. They usually contain humidity.
Hence, dry air is air with no humidity and atmospheric air has humidity.
