Because people are using more hot water for almost everything. For example when someone is cooking with water they are boiling it which is makeing it turn into water vapor.
evaporation is when water vapour rises up and condensation is when water vapour turns into clouds
Water vapour is a constituents in air because water vapour rises in the atmosphere & is always present in the atmospere in some or the other quantity.Also 0.0001% of air consist water vapour
Steam.
Levels of water vapor can decrease due to several factors, including changes in temperature and atmospheric circulation patterns. Cooling temperatures can lead to condensation and precipitation, reducing the amount of water vapor in the atmosphere. Additionally, human activities that impact climate, such as deforestation and changes in land use, can alter local weather patterns and humidity levels. Lastly, seasonal variations can also play a role, with water vapor levels typically decreasing in colder months.
Cloud.
The major factor affecting the amount of water vapour is temperature.
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.
nope.
It is humidity.
Humidity is the amount of water vapour in the atmosphere

Humidity is the measurement of the amount of water vapour in the air.
amount of water vapour in the atmosphere, or in a gas
The amount stays the same but some of it changes to steam and water vapour and it will disappear.
Relative humidity is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure. Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
