Pressure in liquids: Like solids, all liquids and gases (together called fluids), apply pressure. Unlike solids, the liquids do not have a definite shape. They take the shape of the containing vessel. Unlike solids the pressure in the liquids is not the thrust per unit area. It depends upon the depth (height) and the density of the liquid. Solids exert pressure on a surface due to their weight. Fluids also have weight. So, they also exert pressure on the base and walls of container in which they are enclosed. What happens when you fill a balloon with water? The walls of the balloon bulge outwards due to the pressure of the water inside. If you keep on filling water in the balloon, what do you think will happen? The balloon will burst because the pressure on the walls of the balloon will increase beyond what its walls can withstand.
Which of the following are correct : (a) Unlike solids the pressure in the liquids is not the thrust per unit area. (b) Liquids take the shape of the containing vessel. (c) Liquids exert pressure on the base and walls of container in which they are enclosed. | |||

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 was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
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.
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.
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 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
One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
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.
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.
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.
