Question

describe an activity to show that the pressure is liquids increases with depth

Answer 1

$\mathcal{\red{\huge{ACTIVITY:}}}$

◆Take a tin can. And make four holes on it and label than A, B, C and D.
◆ Put cello tape on holes and pour water in the can.
◆ Remove the tape and observe the water coming from the different holes.

$\textbf{\huge{\blue{OBSERVATION:}}}$

◆ We will observe that the water coming from the last hole (D) will cover the maximum distance.
◆ The water coming from the hole (A) will cover the least distance.

$\mathbb{\huge{CAUSE:}}$

◆This is because the pressure in liquid increases with the increase in depth.

Answer 2

Activity: To show that pressure in a liquid increases with depth

Theory: Pressure is force per unit area.

P = gh,

where, P is the water pressure at a particular depth

            g is the acceleration due to gravity

            h is the depth of the water at that point

Materials Required: A plastic bottle, hammer, and nail, ruler

Experiment:

• Make holes of the same size on the bottle with the help of hammer and nail.
• Measure the distance of holes from the bottom with the help of a ruler.
• Now fill the bottle with water.
• Measure the distance from the bottle to the distance up to which the water comes out.

Conclusion: We will notice that greater the depth, greater is the force with which water comes out of the bottle that is the water coming out will travel more distance if the depth is increased.
