Question

In a jar, kerosene is floating on water. Which of the following options is correct?

• A. Density of kerosene is greater than the density of water
• B. Density of kerosene is less than the density of water
• C. Density of kerosene = $2$ ( Density of water)
• D. Density of kerosene = $5$ ( Density of water)

Answer 1

The correct option is B

Density of kerosene is less than the density of water

Floating and sinking are related to the density of the objects. If the density of the body is more than the density of the liquid, the body sinks. If the density of the body is less or equal to the density of the liquid, the body floats. In the above case, the density of kerosene is less than the density of water. So kerosene floats on the surface of water.
