Detailed explanation-1: -These liquids do not mix because they have different densities. Density = mass/volume. The liquids that are more dense are also heavier (per constant volume) and are at the bottom and the liquids that are the least dense will stay on top. Because of the different densities the liquids separate into layers.
Detailed explanation-2: -If you pour together liquids that don’t mix and have different densities, they will form liquid layers. The liquid with the highest density will be on the bottom. The liquid with the lowest density will be on the top.
Detailed explanation-3: -Oil is more dense than alcohol, but less dense than water. The molecules that make up the oil are larger than those that that make up water, so they cannot pack as tightly together as the water molecules can. They take up more space per unit area and are less dense.
Detailed explanation-4: -Pour the fluid into a graduated cylinder and read its volume. Then weigh the graduated cylinder. Then pour the fluid out, and weigh again. The weight of the fluid is the difference between the two weighings.
