describe the following with an activity and draw the diagram liquid exerts pressure on walls of the container
Answers
Explanation:
Activity: A liquid exerts pressure on the walls of its container
Take a plastic bottle.Fix a small glass tube above the bottom of the plastic bottle. We should seal the joint of glass tube with plastic bottle by using molten wax so that water does not leak from the joint. Tie a thin sheet of rubber tightly on the open end of glass tube. Now fill half of plastic bottle with water.On filling water, the rubber sheet tied to the mouth of glass tube gets stretched and bulges out. The bulging out of rubber sheet tied to the glass tube fixed in the wall of plastic bottle demonstrates that water present in plastic bottle exerts pressure on the walls of the bottle. It is the sideways pressure exerted by water which inflates the thin rubber sheet forming a buldge. If we pour more water in the plastic bottle to increase depth, we will see that the bulge in the rubber sheet increases.This indicates that the pressure exerted by water increases with increasing depth.
1)The pressure exerted by a liquid on the walls of container increases with increasing depth.
2)A liquid exerts pressure on the walls of its container.
Activity :A liquid exerts equal pressure at the same depth
Take a plastic bottle.Make 2 small holes of equal size on the two opposite sides of the plastic bottle some distance above the bottom of the bottle. The holes should be at exactly the same height from the bottom of the plastic bottle.Now fill the bottle with water.The two jets of water coming out of the two holes fall at the same distance away from the base on its either side.The two jets of water can fall at equal distance on the two sides of the bottle only if the pressure of water at the depth of 2 holes in the bottle is equal.
We conclude that
1)A liquid exerts pressure on the walls of its container.
2)A liquid exerts equal pressure at the same depth.
The formation of fountains of water from the leaking pipes of water supply pipeline tells us that water exerts pressure on the walls of its container.
Answer:
The pressure exerted by a liquid on the walls of container increases with increasing depth. 2)A liquid exerts pressure on the walls of its container. Take a plastic bottle. Make 2 small holes of equal size on the two opposite sides of the plastic bottle some distance above the bottom of the bottle.
