Is the amount of water vapor in the air compared to the amount of water vapor?
Relative Humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.
Is the percentage of water vapor in the air compared to how much could be in the air at saturation?
100 percent
Relative humidity is the water-vapour content of the air relative to its content at saturation. Saturated air, for example, has a relative humidity of 100 percent, and near the Earth the relative humidity very rarely falls below 30 percent.
How much water vapor is present in the air is?
The percentage of water vapor in surface air varies from 0.01% at -42 °C (-44 °F) to 4.24% when the dew point is 30 °C (86 °F). Over 99% of atmospheric water is in the form of vapour, rather than liquid water or ice, and approximately 99.13% of the water vapour is contained in the troposphere.
Is the amount of water vapor in the air compared to the maximum amount of water vapor the air can hold at that temperature?
Relative humidity
Relative humidity can be defined as the amount of water vapor in air at a given temperature compared to what that air could hold at that temperature.
What is percentage of water vapour in atmosphere?
Water vapor varies by volume in the atmosphere from a trace to about 4%. Therefore, on average, only about 2 to 3% of the molecules in the air are water vapor molecules.
How much water is in the air at 70 humidity?
