Question
Geeta observed a white trail at the back of aeroplane in a clear sky to answer the question from this incident given below.
- What will be the effect of relative humidity of the air surrounding the plane?
- What will be the effect of relative humidity of the air surrounding the plane is low?
- When the air is dry and humid?
Solution
- If the relative humidity of surrounding air is high then, a prominent white trail will be formed. Also, it will take a longer time for the trail to disappear.
- If the relative humidity of surrounding air is low then, a small-sized white trail formed would be formed or it may not get formed at all.
- If the relative humidity of air is more than 60%, air is said to be humid and if relative humidity of air is less than 60%, air is said to be dry.
