Question
Describe an experiment to prove that the pressure in a liquid increase with depth.

Answer
Take a plastic bottle. Punch three holes on its side in the same direction, but at different heights. Now pour some water into it and let it flow through the holes. Observe the flow of water.
Inference:
The water comes out from all the holes with a different force and falls on the table at points that are at variable distances from the bottle. Water from the lowest hole comes out with the greatest force and falls at a point that is at the maximum distance from the bottle. Water from the topmost hole comes out with the least force and falls at the point that is at the minimum distance from the bottle.Your friend was absent from school yesterday. You are enquiring about his absence. He told that he had a fever and it was measured to be 100oC. Is it possible to have a 100oC fever? If he is wrong, try to make him understand.

- Reason:
This activity confirms that the pressure in a liquid varies with the depth of the point of observation in it.
