The correct option is D below a moving fan in the room
The explanation for the correct option
Option (D):
- Evaporation is the process in which liquid changes to vapours at all temperatures.
- It is a surface phenomenon and increases with the increase in temperature, wind speed, and surface area.
- Hence below a moving fan in the room rate of evaporation will be the maximum.
The explanation for the correct options:
Option (A): The rate of evaporation under a tree will be lesser than that of below a moving fan in the room. As this will create a shadow on the pan which will slow down the evaporation process.
Option (B): The rate of evaporation in the open area will be lesser than that of below a moving fan in the room. As it is not mentioned that the open area will have any sunlight or wind, so this case will have a slower evaporation rate.
Option (C): The rate of evaporation in the room will be lesser than that of below a moving fan in the room. As in a room, there will be no sunlight or wind, hence evaporation rate will be less than option (A).
Hence, the correct option is (D).
