Fill air in a balloon and fix pieces of cello tape at different parts of the balloon. Make, small holes using a needle on the balloon at the portions where the pieces of cello, tape are fixed. Fix it on the ‘L’ shaped pipe and fill water in the pipe. We can see, water gushes out in all directions., , To see an experiment related with this topic, click on the following link, , , , NR), , , , h WW. ym/watch Pv: wDA&list=PLIAShZEIXvDIx824xVoLWibM- Ling, What inference do you arrive at from this?, , Liquids exert pressure in all directions., , Activity 2, , _ J Make a few small holes of the same size around a plastic bottle, 3 cm from the bottom., Pour water into the bottle. Water gushes out through all the holes with equal speed., , Inference: Liquids exert pressure in all directions. Liquid pressure is equal at same depth., , To see an experiment related with this topic, click on the following link, httos://www.voutube.com/watch?v=GmEMdixnQ8M &list=PLOAShZEiXvDIx824xVoLWibM -pSFuCgOa&index=23, Depth and pressure, , Make 3 holes in equal distance from each other upwards from the bottom of a long (, plastic bottle. Fill the bottle with water keeping the holes closed. Observe the flow of, water coming out., , , , * Does the water coming out through all the holes fall at the same distance?, , No. Water coming out from the top hole falls to less distance and from the bottom hole to more, distance., , © What, , , , the change in liquid pressure towards the bottom?, , Water pressure increases towards bottom., , , , A0GIINGTBBIOS &)5)068 all Wlagad. anweRegio Afwlemoag}o esdle6o08 TECH Malappuram wombioows0, ald &)50GO AaMlafla WOT OOala] Gqfeqieqyodles wolmjo woedeenrd oaxdas onbqyors oaxmye., https://play.google.com/store/apps/details m.basith.sasthracheppua|, , , , , , Pg, , ‘TECH Malappuram (Teacher Empowerment through Co-operation and mutual Help), , , , els there any change in the flow of water when its level in the bottle falls?, Yes. As the water level falls, the speed of flow of water decreases., , Inference: Liquid pressure increases with the increase in depth., , , , g air bubble, , Take a vessel full of water. Keep one end of a thin plastic tube at the bottom of the vessel. Blow ai, gently through the other end., , Is there any change in the size of the bubbles rising from the bottom to the top? What might be, the reason?, , Yes. The size of the bubbles increases as they rise. This is because, the liquid pressure deceases, towards the top level.
