The oil is floating on water, so it density is lower than that of water.
salt water has a lower density than the other types of water.
The lowest density in water occurs at 4 degrees Celsius, where water is most dense. As water cools below or heats above this temperature, its density decreases, causing it to expand and become less dense.
Ice has the lowest density among the different forms of water. This is because when water freezes into ice, the molecules arrange themselves in a lattice structure that causes the ice to take up more space compared to liquid 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.
Salt water has a higher density than both mineral water and air. Mineral water has a lower density than salt water but higher than air. Therefore, air has the lowest density among the three.
It dosent, waters density is lower then cooking oil, resulting in cooking oil floating on water
It doesn't. Cooking oil doesn't dissolve in water and therefore doesn't affect the chemistry of the water.
Pumice is a type of volcanic rock that has the lowest density and can even float on water due to its high amount of air pockets.

All the gas giants; in our Solar System, Saturn has the lowest density (less than the density of water).

Well, darling, oxygen is the lightest of the bunch with a density lower than the others. So, if you're looking for the one with the lowest density, oxygen is your winner. But hey, don't underestimate the importance of staying hydrated with some good ol' water, too.
