The following experiment demonstrates that liquid pressure depends on the density of liquid:

Describe an experiment to show that liquid pressure depends on the density of liquid. Force and Pressure, Concise Physics Solutions ICSE Class 8.
  1. Take two identical glass tubes open at both the ends. Mark them A and B.
  2. Hold both the tubes vertically and tie an inflated balloon to both the tubes at their lower ends.
  3. In tube A pour some water.
  4. 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.
