Reva carried out an experiment, she took a watered potted plant and placed it on a sheet of glass and covered it with a bell jar. The edge of the bell jar is sealed with vaseline to make it airtight.The whole apparatus is then placed in a sunny place for an hour or two.What are the observations made by Reva at the end of this experiment?
The inner walls of the bell jar get accumulated with drops of moisture.
After an hour or two, it is observed that the inner wall or inner surface of the bell jar is bedewed with moisture.The plant kept inside the bell jar gets rid of the excess of water in the form of vapour through the leaves. This gradually saturates the air inside the bell jar and when the vapour comes in contact with the cool surface of the bell jar, it condenses on the inner surface of the bell jar appearing as tiny droplets.
