ACTIVITY 2:Water Flow Magic
small nail, water
• Procedure:
Make a small hole near the bottom of the water bottle using a
nail.
• Make a small hole near the top of the bottle with the nail
Tighten the lid on the bottle.
Now lets move close to a sink.
Remove the tape from the lower hole and observe what happens.
• Does the water come out??
.Now remove the tape from the upper hole also
The water stars coming out of the lower hole.
Now cover the upper hole with your thumb. The water stops
coming out of the bottle This way we can control the flow of
water.
PL ANSWER THIS I WILL MARK THE FIRST CORRECT ANSWER AS BRAINLIEST
AND GIVE 5 STARS
AND FOR FALTU ANSWERS I WILL REPORT THEM
Find out the reason behind this activity and record in your physics
notebook
• MATERIAL REQUIRED: Plastic water bottle with a tight fitting lid,
• Close both the holes with cello tape and fill the bottle with water.
Answers
Yes we can control the flow of water by the following activity.
Actually I did not understand the question you asked but I'll say what I understood.
We can stop the flow of water by placing an obstacle in the middle and we understood that water can flow through a small hole also.
Answer:
We observe that when we remove the tape from the lower hole only, water hardly comes out or no water at all but when we remove the tape from lower and upper hole both, water from the lower hole comes out with higher speed.
Explanation:
When we removed the tape from lower hole only, we can see that few drops of water falls down which is obviously due to gravitational force and when we remove the tape from upper hole also, the water comes out with higher speed because both air pressure and gravitational force acts on the water.
