Describe an activity to show liquid exerts pressure on walls of container also on the side of container.
Answers
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. 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.
an activity to show that liquid exerts pressure on the wall of the container and also on the side of the container.
Procedure: pick a glass beaker. Feel it with water. Now take a drill machine and drill on the side of the beaker.
Observation: it is seen that there is projectile movement of the water after there is drilling and making of a hole on the side of the glass beaker.
Inference: this shows that there has been a force which has been applied on the water molecule because of which it is moving in a projectile motion. Now the pressure is the force per unit surface area of the hole.
