Question

d. On what basis and how will you determine whether air is saturated with vapour or not?

Answer 1

• On the basis of amount of water vapours present in the air, it can be either saturated or unsaturated.
• If the amount of water vapours exceeds the amount that the air can contain, then it is called saturated.
• If the amount of water vapour is less than the limit of the amount that air can contain then it is called unsaturated.
• We can determine whether the air is saturated with vapour or not in terms of relative humidity.
• If the relative humidity is 100%, the air is saturated with water vapour
• If the relative humidity is less than 100%, the air is not saturated with water vapour.
