Question

Distinguish between Absolute Humidity and Relative Humidity.

Answer 1

Difference between absolute Humidity and Relative Humidity:

• When the weight of water vapour expressed with respect to the unit volume of air is called absolute humidity. on the other hand relative humidity is the ratio between the water vapour actually present in the air and its capacity to hold water vapour at a given temperature.
  
• In Absolute humidity, the weight of water vapour is taken in grams and the volume of air is in the cubic meter. On the other hand, in relative humidity, the actual presence and the capacity is always expressed in percentage.
