decreases with increase in humidity​

Answer 1

Answer:

I wish this helps.

Explanation:

As humidity increases velocity of sound

Speed of sound in air increases with the increase in humidity in air. The density of water vapour is about 5/8th times the density of dry air at ordinary temperature, therefore the increase of moisture in air tends to decrease the density of air.

Answer 2

Answer:

The velocity of sound increases with increase in humidity .
