Variation Of Pressure In Liquids With Depth: When we swim in a river, we feel the water pressure acting against our eardrums. The deeper we swim, the greater the pressure. The cause of this pressure is the weight of the fluid, water plus air directly above us. As we swim deeper, there is more water above us. Therefore, there is more pressure. If we swim twice as deep, there is twice the weight of water above us, so the water's contribution to the pressure felt by us is doubled. The pressure due to a liquid also depends upon its density.
Activity: To understand the pressure exerted by water. Aim: To prove that liquids exert pressure. Materials Required: A glass test tube with open ends, balloon with water. Procedure: Tie a balloon to the lower end of the test tube. Hold the tube vertically and pour some water into it. You will observe that the rubber membrane of balloon bulges out. Now add more water. The rubber membrane bulges more. Again, if you pour more water in the test tube the rubber membrane bulges more. Conclusion: So, this concludes that pressure exerted by a liquid increases with the height of the liquid column. |
Pressure at a depth in a liquid depends upon two factors:
The depth of liquid increases, the weight of liquid column pushing down from above increases, and the pressure _________________________. | |||

Abhyas is a complete education Institute. Here extreme care is taken by teacher with the help of regular exam. Extra classes also conducted by the institute, if the student is weak.
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
I have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
It has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
Abhyas Methodology is very good. It is based on according to student and each child manages accordingly to its properly. Methodology has improved the abilities of students to shine them in future.
About Abhyas metholodology the teachers are very nice and hardworking toward students.The Centre Head Mrs Anu Sethi is also a brilliant teacher.Abhyas has taught me how to overcome problems and has always taken my doubts and suppoeted me.
It was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
My experience was very good with Abhyas academy. I am studying here from 6th class and I am satisfied by its results in my life. I improved a lot here ahead of school syllabus.
