Question

Oil and water do not mix together. Oil floats on the water's surface. Why is this so?

Answer 1

Water is denser than water

Step-by-step explanation:

All liquids have different densities and can be separated based on the different densities. If you put vinegar and water together, you can mix them- but if you let it sit it will eventually separate again. The same goes with oil. Its density is different from water.

Answer 2

oil floats on the water’s surface due to the oil being less dense than the water it was spilled into.
