Interpretation:

The reason due to which oil floats on water needs to be explained.

Concept introduction:

Oil is a viscous liquid. It is derived from petroleum and is especially used for fueling or lubricating. It is non-polar in nature.

Expert Solution & Answer

Answer to Problem 8SSC

Oil does not sink in water and creates a layer on the surface of the water as the density of water is more than that of oil.

Explanation of Solution

Oil is a non-polar substance and acts a viscous liquid at surrounding temperatures. Oils could be of animal, vegetable or petrochemical. It is either volatile or non-volatile. Oil is used for food such as olive oil, for fueling such as heating oil or for medical purposes such as mineral oil and for lubrication such as motor oil.

Oil floats on water because it is less dense than water and creates a layer on the surface of the water. For materials to sink in water, density of the material should be more than water.

Conclusion

Thus, oil floats on water because its density is lesser than that of water.
