Question

Oil floats on water because oil is more dense than water.

• A. True
• B. False

Answer 1

The correct option is B False

1. An object floats on a liquid when the weight of the object balances the upward push of the liquid or if the object is less dense than the liquid it is immersed in.
2. Oil is lighter than water.
3. It floats over water because its density is less than that of water.
4. The molecules that form oil are larger than those that form water, so they cannot pack as tightly as the water molecules.
5. They take up more space per unit area and are less dense.

Hence, the given statement is false.
