because of the density i the water, i think?
For when your cooking and you need water.
The liquid with the highest density will sink to the bottom, while the one with the lowest density will float on the top. The order of stacking will be based on the density of the liquids, with the densest at the bottom and the least dense on top.
oil
One example of a liquid with a density less than water is vegetable oil. This means that a given volume of vegetable oil will weigh less than the same volume of water.
There are microscopic bubbles of air trapped in the ice - making it lighter than the water.
I can only assume that you mean which has the grater desity water or boiling water. The colder the water the more density it will have.
The density of water is close to the average density of most common liquids. However, the density of water (1 g/cm^3) is slightly lower than the average density of liquids, which can vary from 0.7 g/cm^3 to 2.2 g/cm^3 depending on the substance.
It dosent, waters density is lower then cooking oil, resulting in cooking oil floating on water
No, liquids with the highest density generally sink to the bottom of a container, while those with lower density float on top. This is due to the principle of buoyancy, where denser substances displace lighter ones.
Some liquids sink in other liquids due to differences in density. When a liquid is denser than the liquid it is placed in, it will sink because of gravity. This is similar to how some objects sink or float in water based on their density compared to the water.
It doesn't. Cooking oil doesn't dissolve in water and therefore doesn't affect the chemistry of the water.
