Question

with increasing of humidity the rate of evaporation​

Answer 1

Answer:

Humidity, or water vapor content of the air, also has an effect on evaporation. The lower the relative humidity, the drier the air, and the higher the evaporation rate. Wind moving over a water or land surface can also carry away water vapor, essentially drying the air, which leads to increased evaporation rates.

Answer 2

Answer:

If we are saying that air humidity is high, then the amount of water vapour is high in air. So, now water vapour intake capacity of air is decreased. But evaporation is the process by which extra water vapour is added to the atmosphere. So, naturally with more humidity the evaporation rate decreases.
