Take an empty bottle of the sort inwhich bottled water is sold. Pour about5-10 mL of water into it and close thebottle tightly. Shake it well or leave itout in the Sun for ten minutes. Thiscauses the air in the bottle to besaturated with watervapour.
Now, take a lighted incense stick. Openthe cap of the bottle and allow some ofthe smoke from the incense stick toenter the bottle. Quickly close the bottleonce more. Make sure that the cap isfitting tightly. Press the bottle hardbetween your hands and crush it asmuch as possible. Wait for a fewseconds and release the bottle. Againpress the bottle as hard as you can.
Now answer
1.When didyou observethat theairinside seemed to become foggy?
2.When does this fogdisappear?
3.When is the pressure inside the bottlehigher?
4.Is the fog observed when the pressurein the bottle is high or when it is low?
5.What is the need for smoke particlesinside the bottle for this experiment?
6.What might happen if youdotheexperiment without the smoke from theincense stick?
Now try it and check ifthe prediction was correct. What mightbe happening in the above experimentin the absence of smoke particles?
Examples for non leguminous plants.
what r the harmful effect of global warming ?
Ways to prevent soil erosion.
