Hi friends I am Nandiniwelcome to avulkids
today I am going to show you experiment based on vacuum .for this you
need a white plate , some colored water matches and a candle .so
what is vacuum , vacuum is anything from which all the matter has been taken out.
first light of the candle then put some drops of candle on the plate and then
fix the candle.wait for few minutes and let it dry
once the candle is fixed on the plate then carefully pour some colored
water inside the plate .After pouring
water in the plate carefully cover the
candle with the empty glass Observe what happenes As you can see the candle extinguishes itself.This happens because the candle needs oxygen to burn and when
we cover the candles with the empty glass the candle uses all the oxygen
available inside the glass and when the oxygen is all used up ,
extinguishes .Now the air pressure inside the glass is low and the air is
lighter and the air pressure outside the glass is higher and the air is heavier
this causes
vacuum and makes the water rise up in the glass.Thanks watching
