Question

The diagram below shows two identical glass tubes A and B tied with balloons at one end. Water is poured in tube A whereas kerosene is added in tube B. It is observed that bigger bulge is produced in tube A. Which of the following could explain this fact?

Solution

The correct option is B

Water has more density than kerosene oil


Liquid pressure depends upon the density of the liquid. It is observed that a bigger bulge is produced in tube A in which water is filled. This bigger bulging is due to the fact that water is heavier than kerosene oil because it has a higher density than kerosene oil.

Q. An open-ended U-tube of uniform cross-sectional area contains water (density 103kgm−3). Initially the water level stands at 0.29 m from the bottom in each arm. Kerosene oil (a water-immiscible liquid) of density 800kgm−3 is added to the left arm until its length is 0.1 m, as shown in the schematic figure below. The ratio (ℎ1/ℎ2) of the heights of the liquid in the two arms is

Q. Fig(a) shows a U-tube of uniform cross-section that is open at by both ends. It is partially filled with water. Now a liquid of density is 'd1' id poured into the left arm. The liquid does not mix with water. It is observed that height of liquid surface in the left arm is 2cm more than the height of water surface in the right arm as shown in figure. Take density of water as 1000kg/m3. Find density of the liquid d1.
