Q1-Describe an activity to show that:
(a) The pressure exerted by a liquid
at the bottom of container,
depends on the height of it
column.
(b) Liquids exert pressure on the
walls of container.
(c) Liquids exert equal pressure at
the same depth.
Someone pls tell me properly.
With labelled diagrams
Thnxs
Fast pls
Answers
Explanation:
All the liquids exert pressure on the base or bottom and walls of their container.All the liquid have weight.
When we pour liquid into a vessel, then the weight of liquid pushes down on the base of the vessel producing a pressure.
The liquid exerts pressure on the base of the vessel.
The pressure exerted by a liquid changes with depth in the liquid. The pressure exerted by a liquid increases with increasing depth inside the liquid. The pressure exerted by a liquid is small just under the surface of the liquid. But as we go we deeper in a liquid the pressure of liquid increases.As the depth of liquid increases the weight of liquid column pushing down from above increases and hence the pressure also increases.
Activity: The pressure of liquid increases with depth
A tall vessel has short and thin tubes fitted at different depth from the top of vessel.The three tubes are of equal diameters and corks are fitted into them.The vessel is filled with water and then all the corks are removed quickly. On removing the corks the water from uppermost tube is found to travel the shortest distance from the base of the vessel ,the water from middle tube goes a little farther away whereas water from the lowermost shoots out farthest all. The depth of water near uppermost tube is small so the water comes out from uppermost tube with smaller pressure and falls near the bottom of the vessel.The depth of water near middle tube is greater so the water comes out with greater pressure from middle tube and falls farther away from the base of vessel. The depth of water near lowermost tube is the greatest so the water comes out of lowermost tube with the greatest pressure and goes farthest from the vessel. As the depth of water increases the pressure of water gradually increases.
Answer:
the pressure exerted by a liquid at the bottom
