Activity
✍️Take a few drops of spirit into Patra dishes separately .
✍️Keep one of the dishes containing spirit under a ceiling fan and switch on the fan .
✍️keep another dish with lid closed .
✍️ observe the quantity of spirit in both dishes after 5 minutes .

✍️This is because any molecule escaping from the surface is blown away from the vicinity of the liquid .
✍️This increases the rate of evaporation .
✍️This is the reason why the spirit in the battery dish that is kept under ceiling fan evaporates quickly when compared to that kept closed .
Answer:
You can take 2 wet cloths and place one under the fan and another under a table.

Explanation:
The particles of water are continuously jumping on the surface of the cloth and are trying to get out.
The high wind speed facilitates this and the drops are gradually carried away with the wind
