Earth science

1 Answer:-
The smaller the difference between wet & dry temperature, higher will be the humidity. Dry
temperature is the simply ambient temperature or temperature of the dry air. Wet temperature
leaves a cooling effect after evaporation. Relative humidity (RH) represents the amount of water
present in the air.
 Air moisture increases then Evaporation rate will be decreases.
 If Dryness of Air increases then Cooling effect also increases (Higher will the drop down
between temperature)
 Relative Humidity increases when drop down decreases.
 At 100% Relative Humidity no drop down [Wet temperature become equal to Dry
Temperature]
