What is relative humidity?

What is Absolute humidity?
What is Specific humidity?
But can you give me an answer a paragraph long each thanks a lot!
Or just answer 1 or 2 of my questions I will take any answer!!

P.S- Thank you so much for your help!!

Relative humidity is a measure of the amount of water vapor present in the air compared to the maximum amount the air could hold at that temperature. It is expressed as a percentage. Relative humidity is influenced by both temperature and moisture content in the air. To calculate relative humidity, you need to know the current air temperature and the wet bulb temperature or dew point temperature. You can use a hygrometer or a psychrometer to measure these temperatures. Once you have the values, you can calculate relative humidity using the appropriate formula.

Absolute humidity is a measure of the total amount of water vapor present in the air, regardless of temperature. It is expressed in grams of water vapor per cubic meter of air. Absolute humidity gives you the actual amount of moisture present in the air, which can be important in certain applications like industrial processes, food storage, or meteorological analysis. To measure absolute humidity, you need a hygrometer or a device called a humidity sensor that can directly measure the water vapor content.

Specific humidity is a measure of the actual mass of water vapor present in a given mass of air. It is expressed in grams of water vapor per kilogram of air. Specific humidity is independent of temperature and is commonly used in meteorological analysis. To calculate specific humidity, you need to know the mass of water vapor present in a given mass of air. This can be determined by dividing the mass of water vapor by the total mass of air. Specific humidity provides a useful measure of the moisture content in the atmosphere, especially in applications where temperature variations are not considered.
