Answer 1

Answer:

To show : - Pressure exerted by a liquid is directly proportional to its density

Procedure: -

• Take two identical balloons attached to one end of each of two identical glass tubes opened at both ends.

• Fill one tube with milk and another with alcohol to the same height.

Observation - It can be seen that the balloon attached to the tube with milk bulges out more than the balloon attached to the tube with alcohol.

Result: -This shows that the same height of milk exerts more pressure than alcohol. Since the density of milk (1.03) is more than the density of alcohol (0.8), i.e, Pressure exerted by a liquid is directly proportional to its density
