Question

define relative humidity.On what basis and how will you determine whether air is saturated with vapour or not ?​

Answer 1

Explanation:

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 will be saturated otherwise not.

Answer 2

Answer:

Definition: the amount of water vapour in the air as a percentage of the amount required for saturation at the same temperature.

Explanation:

1. The relative humidity of the air determines whether or not it is saturated with water vapour.

2. The air is saturated with water vapour if the relative humidity is 100 percent.

3. We perceive the air to be humid if the relative humidity is more than 60%.

4. We consider the air to be dry if the relative humidity is less than 60%.
