Water vapor in the air is water in the form of a gas.
a cloud
Humidity means the amount of water vapor in the air. It begins with the letter H.

Air that has reached its water-vapor capacity is said to be saturated.
Its ratio of the air's water vapor content to its water vapor capacity :)
Air that has reached its water vapor capacity is considered saturated. This means that the air cannot hold any more water vapor at its current temperature and pressure, leading to condensation or precipitation.
When the air is filled to capacity with water vapor, it is said to be saturated. This occurs when the air's humidity reaches 100%, and any additional water vapor will result in condensation, such as forming clouds or fog.
The amount of water vapor that air can hold depends on its temperature. Warmer air can hold more water vapor than cooler air. This relationship is described by the concept of relative humidity, which is the ratio of the amount of water vapor present in the air to the maximum amount the air could hold at that temperature.
The amount of water vapor an air mass can hold is primarily determined by its temperature and pressure, following the principles of the Clausius-Clapeyron relationship. Warmer air can hold more moisture, while cooler air holds less. Additionally, humidity levels indicate how saturated the air is with water vapor, which is influenced by temperature and the presence of water sources. Thus, the capacity for water vapor in an air mass increases with rising temperatures.

The ratio of air's water-vapor content to its capacity to hold water vapor at that same temperature is relative humidity. It is expressed as a percentage and indicates how close the air is to saturation with water vapor. A relative humidity of 100% means the air is fully saturated and cannot hold any more water vapor at that temperature.
