Question

A mixture of kerosene oil and water is an example of immiscible liquids. When left undisturbed, they form separate layers of oil and water. Can you identify which liquid comes to the bottom and which will be at the top?

• A. Water comes at the top and kerosene at the bottom
• B. Water settles at the bottom and kerosene comes at the top.
• C. Top - Kerosene; Middle - Water; Bottom - Kerosene
• D. Both get mixed well and it cannot be identified

Answer 1

The correct option is B Water settles at the bottom and kerosene comes at the top.

It is based on the density of the liquids. The liquid that is lighter (lesser density) goes over the top of the other liquid having higher density.
In this case, kerosene has density of 820 kg/m3 and water has 1000 kg/m3. So, kerosene remains at the top side.
