Question

Take 4-5 plastic bottles of different shapes and sizes. Join them
together with small pieces of glass or rubber tube as shown in Fig.
11.11. Keep this arrangement on a level surface. Now pour water in any
one of the bottles. Note whether the bottle in which water is poured gets
filled first or all the bottles get filled up simultaneously. Note the level of
water in all the bottles from time to time. Try to explain your
observations. [1x4=4]

(i) Which bottle will get filled up at first?
(ii) Instead of water if petrol is poured then which bottle will get filled up
first?

(iii) If the water is poured from the bottle A then which bottle will filled up
first?
(iv) What can we conclude from the above experiment?

Answer 1

Answer:

If the bottles are on the same level surface then the level of water in all the bottles will same. Therefore all the bottles will get filled together.

The water transfers from the first bottle to the rest and the level rise together.

Hence, the level of water will rise together in all the bottles. No specific bottle gets filled first.
