22:54​

Answer 1

Answer:

1) A quantity representing the amount of water vapor atmosphere or in gas.

2) Air that contains the maximum amount of water vapour that is possible at the given temperature and pressure, i.e., air in which the relative humidity is 100%.

3) Absolute humidity refers to the amount of water contained in the parcel of air and is commonly measured in grams of water per kg of dry air

4) The amount of water vapour present in the air expressed as the percentage of the amount needed for saturation at the same temperature.

Explanation:

A) Formula of Relative Humidity is:-

RH = 100 × Specific humidity/Absolute humidity

B) Formula for Absolute Humidity is:-

AH = mH2O/Vnet
