A) Evaporation causes cooling because during evaporation the particle of the liqued absord energy from the surroundings to regain the energy lost during evaporation. the absorbtion of heat from the surrounding makes the surrounding cool.
B) When the humidity level goes down, it means that the amount of water vapours will go up.
This in turn implies that the air particles do not have the capacity to hold any more water particles and this is when the rate of evaporation does down or decreases.
Filling the gaps becomes time taking thus decreasing the evaporation.
