Physics
Describe a suitable experiment to demonstrate that a liquid exerts pressure sideways also.
Answer
The following experiment demonstrates that a liquid exerts pressure sideways also:
- Take a glass tube closed at one end and having an opening in its side near the bottom.
- Tie a deflated balloon at the side opening of the tube.
- Hold the tube vertically straight as shown in the above figure.
- Pour some water in the tube.
Observations — After sometime we will notice that the balloon bulges out as shown in figure (b) above.
Conclusion — From the above experiment it is concluded that a liquid exerts pressure sideways also.
