Question

Kerosene floats on water because

• A. Kerosene has more density
• B. Kerosene has less density
• C. Densities of water and kerosene are equal
• D. Water has more density

Answer 1

Answer: (B), (D)

Water has more density

Explanation:

1. Kerosene is less dense than water.
2. The density of water is $1000\raisebox{1ex}{$kg$}\!\left/ \!\raisebox{-1ex}{$m^3$}\right.$ and kerosene is $810\raisebox{1ex}{$kg$}\!\left/ \!\raisebox{-1ex}{$m^3$}\right.$.
3. When something has less density than the water then it floats on water. Hence, kerosene floats on water.

Hence the correct options are options B and D.
