💧 EXPERIMENT on the Density of LIQUIDS Water Oil Alcohol 🧪

Hello friends, we are Water, Oil and Alcohol and today we will try to find out what our density is to understand who of us is heavier and who is lighter. Follow us! You should know that DENSITY means the ratio between the mass of a body and its volume and is measured in g/ cm3. 🧪 FIRST EXPERIMENT with water and oil Pour tap water into a glass. Then, pour olive oil into the same glass. As you can see, oil floats on water because it is lighter than water, which instead sinks. This means that oil has a lower density than water. In fact, while water has a density of 1 g/cm3, olive oil has a lower density, equal to 0.9 g/cm3 ⚗ SECOND EXPERIMENT with oil and alcohol Let's try now with denatured alcohol. Pour the red alcohol into a glass. Then, in the same glass, pour the olive oil. This time the oil does not float, but sinks to the bottom. The alcohol, on the other hand, remains on the surface. This means that the alcohol is lighter than the oil. In fact, alcohol has a lower density than oil. In particular, while olive oil has a density of 0.9 g/cm3, the density of denatured alcohol is 0.8 g/cm3 Therefore, if we order all these liquids from the least dense to the most dense, we will have: Alcohol 0.8 g/cm3 Oil 0.9 g/cm3 Water 1 g/cm3 We can therefore say that alcohol, oil and water are also arranged in order from the lightest, which floats on the others, to the heaviest, which sinks. Let's check it out! 👨‍🔬 THIRD EXPERIMENT with STRATIFICATION of alcohol, oil and water Take a glass and pour some tap water into it. Then pour in the oil. As we have already seen, the oil floats on the water because it is lighter and less dense than the water which instead remains at the bottom. But if at this point we pour the alcohol a little at a time, without going beyond the layer of oil, we will notice that the alcohol actually floats on the oil because it is lighter, and therefore less dense, than both the water and the oil itself. Did you see what a beautiful stratification? Our data on density are therefore confirmed and the respective liquids are distributed in the glass from the least dense, that is, the red alcohol which floats on all the other liquids, to the most dense, that is, the water, which sinks under the oil and the alcohol We have therefore discovered that, for the same quantity, different liquids have different weights, due to their different densities. Liquids with a higher density weigh more and sink, while those with a lower density, weighing less, remain in the upper layers. Is everything clear guys?
