Answer
The following experiment demonstrates that liquid pressure depends on the density of liquid:
- Take two identical glass tubes open at both the ends. Mark them A and B.
- Hold both the tubes vertically and tie an inflated balloon to both the tubes at their lower ends.
- In tube A pour some water.
- In tube B pour some concentrated sugar solution such that its height is same as that of height of water in tube A.
Observation — It is noticed that the balloon attached to tube B bulges out more as compared to balloon attached to tube A as shown in the above figure.
Conclusion — Density of sugar solution is more than water so it exerts more pressure which shows that liquid pressure depends on the density of liquid.
