The measure of water vapor in the air is called humidity. It is commonly expressed as a percentage, known as relative humidity, which indicates the amount of moisture present in the air compared to the maximum amount the air can hold at a given temperature. Absolute humidity, on the other hand, measures the actual mass of water vapor present in a given volume of air.
Relative humidity is a measure of the amount of water vapor content in the air compared to the maximum amount of water vapor that the air can hold at a specific temperature. It is expressed as a percentage and provides insight into how close the air is to being saturated with moisture.

You can demonstrate that the atmosphere contains water vapor by using a simple experiment involving a clear glass jar and a small amount of ice. Place ice in the jar and observe the condensation that forms on the inner walls as the ice cools the air, causing water vapor to condense into liquid water. Additionally, hygrometers can measure humidity levels, providing a quantitative measure of water vapor in the atmosphere. Lastly, observing weather phenomena like clouds and fog also indicates the presence of water vapor in the air.
The amount of water vapor in the air is known as humidity, and it is usually measured in terms of relative humidity as a percentage. The maximum amount of water vapor that air can hold is influenced by temperature, with warmer air able to hold more water vapor than cooler air. This relationship is described by the concept of saturation vapor pressure.
When air holds the maximum amount of water vapor it can, we say it is saturated.
The measure of the amount of water vapor in the atmosphere is called humidity. It is typically expressed as relative humidity, which is the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a specific temperature.
The instrument used to measure the amount of water vapor in the atmosphere is called a hygrometer. It works by calculating the humidity levels in the air based on factors like temperature and the amount of water vapor present.
Relative humidity is a measure of the amount of water vapor in the air. It represents the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a specific temperature, expressed as a percentage.
The measure of water vapor saturation of air is called relative humidity. It is expressed as a percentage representing the amount of water vapor present in the air compared to the maximum amount it can hold at a given temperature.

This is called the absolute humidity, usually expressed in grams of water vapor per kilogram of air, but also by water vapor per unit volume of air (e.g. grams per cubic meter).
The amount of water vapor present in air is called humidity. Humidity is a measure of the water vapor content in the air, expressed as a percentage relative to the maximum amount of moisture that the air can hold at a specific temperature.
