Because the evaporation of water depends on many factors: temperature, pressure, winds, bodies of water.
because inhale air is oxygen and due to that we stay alive
The major factor affecting the amount of water vapour is temperature.
An atmospheric river is a narrow and long band of atmospheric moisture which transports lots of water vapour from the tropics in a manner similar to how a terrestrial river transports water.
It varies. There is no single percentage value
nope.
It is humidity.
Humidity is the amount of water vapour in the atmosphere

Humidity
Relative Humidity is the measure of water vapour in air. It is the ratio of the actual water vapour in air divided by the maximum amount the water the air can hold at the existing temperature and pressure. It tells how fast or slow the water on the body or in clothes will evaporate or in otherwords is the air dry or humid. Absolute measure of water vapour in air is called specific humidity. It can be measured as ratio of mass of water and mass of dry air.
Humidity is the measurement of the amount of water vapour in the air.
Water vapour doesn't boil, but liquid water's boiling point is 100 degrees C, or 212 degrees F.boiling point is that point at which the vapour pressure of a liquid become equal to the atmospheric pressure at a particular temperature.for exampleboiling point of water is 100 degree Celsiusthat isat this temperature vapour pressure of water is equal to the atmospheric pressureso there is no boiling point of water vapour since it is not a liquid and boiling point is only determined for liquids not gases or vapours .also vapour has 540 kilo calories of heat known as latent heat of vapourisation at 100 degree celsius.
