Answer:
Velocity of sound wave is directly proportional to the humidity in the air. As the water vapor content in air decreases i.e humidity decreases, velocity of sound also decreases.

___________________________________☺️
1. The humidity of the air in the region of this evaporation is reduced, which allows more water molecules to dissipate into the air.
2. Wind can also change the vapor pressure by moving air about rapidly, thereby causing it to expand.
