Kerosene was poured into a beaker, and then water was added. how will the liquid be located in it? why?

The kerosene will be on top (in the beaker) and the water will be on the bottom. This is due to the fact that the density of water is 0.9982 g / cm, and the density of kerosene is 0.78-0.85 g / cm. Liquids are arranged in layers – at the top there will be a liquid with the lowest density (kerosene), at the bottom with the highest (water). this is possible because liquids do not mix.
