A liquid of lower density floats above a liquid of higher density. Here is how different liquids looked when they were poured carefully into a beaker. What can be said about water in comparison with these liquids?

Water is most dense.

Explanation:

Water is made up of hydrogen and oxygen atoms. Oxygen is smaller than carbon and its quite heavier, and the volume of water molecules is greater than the volume of oil molecules. It makes the water thicker than gasoline. Water molecules are therefore very attracted to one another and stack quite close around each other. This is another reason why water is denser than oil. in the same way, the water has more mass than an equal volume of alcohol and therefore it must be denser.
