So that air should not enter the jar and medium inside the bell jar must become air-free.

Good evening friend!
Vaseline is applied to the brim of the jar in the bell-jar experiment because it is involved in all the joints in the experimental set-up, thereby making the set-up air-tight, to prevent any extra CO2 from air interfering with the experimental results.
Thank you!
Hope my answer helps you!

pranaymayal17:
what happens then
Then air inside the jar will be CO2
to usse transpiration ka kya relation he
The extra CO2 coming in helps the plant to photosynthesise.
And also moisture enters along with air
which can interfere with the result that plants transpire and release water vapour.
