Question

Four different liquid substances (fresh water, oil, mercury, blood) of equal volumes are placed in one transparent rectangular container. The mixture formed distinct layers. How will the layers be arranged from top to bottom?

Answer 1

The density of a pure material is equal to its mass concentration in numerical terms. Varying materials have different densities, which can affect things like buoyancy, purity, and packaging. At normal temperature and pressure, osmium and iridium are the densest known elements.

Complete answer:
The density of a material is its mass per unit volume (more specifically, its volumetric mass density; also known as specific mass). Although the Latin letter D can also be used, the sign for density is (the lowercase Greek letter $\rho$ rho). Density is defined mathematically as mass divided by volume:
$\rho =\dfrac{m}{V}$
, where V is the volume, m is the mass, and $\rho$ is the density. In certain situations (for example, in the oil and gas sector in the United States), density is informally described as its weight per unit volume, which is technically incorrect - this quantity is more precisely known as specific weight.
The liquids with the highest density are also the heaviest (per constant volume) and will sink to the bottom, while the liquids with the lowest density will rise to the top. The liquids split into layers due to their differing densities. Corn syrup is the heaviest and hence comes in last. Corn syrup is lighter than water, while oil and alcohol are heavier. We discovered that, despite the fact that the oil was poured last, the water was heavier than the oil and forced the oil to the top. The lightest substance is alcohol, which floats to the top.
The things that are dropped in will settle on the first layer, which has a higher density than itself, and under a lighter solution. Because a bolt has a larger density than the rest of the liquids, it sinks to the bottom. Because the pasta has a lower density than alcohol, oil, or water but a higher density than corn syrup, it floats on top of it. Because a cork is less thick than all of the liquids, it floats on the alcohol's surface.
Because mercury has the highest density, it will sink to the bottom.
Water, red and white blood cells, plasma, and dissolved compounds including sugar, lipids, and proteins make up blood.
This combination has a density of 1.4 g/ml, which is greater than fresh water's density of 1 g/ml.
Fresh water will come in third, with a density lower than oil.
Because oil has a lower density than water, it floats.
Mercury, Blood, Fresh Water, and Oil will be the layers.

Note:
Temperature and pressure affect the density of a substance. For solids and liquids, this variance is generally minor, but for gases, it is significantly higher. When you apply more pressure on an object, it shrinks in volume and so becomes denser. With a few exceptions, increasing the temperature of a material reduces its density by increasing its volume. Heating the bottom of a fluid causes heat to convect from the bottom to the top in most materials due to a reduction in the density of the heated fluid. As a result, it rises in comparison to more dense unheated material.
