Is oil less than dense than water?
How are oil and water molecules different from each other?
Why does oil float on the surface of water?
In general the relative density of most oils, both mineral and vegetable, is between 0,840 and 0,960….Density of some vegetable oils:
Does oil have a greater mass than water?
Likewise, if the mass decreases but the volume stays the same, then density goes down. Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids….How Does It Work.
The density of liquid water is about 1 g/cm3 while that of vegetable oil is 0.93 g/cm3. Because vegetable oil is less dense it floats on top of water.
To answer the first question: When oil floats, it is generally because the oil is less dense than the water it was spilled into. The more salt is dissolved in water, the greater the water’s density. This means that saltwater is denser than freshwater.
Since the oil is lighter, it is less dense than water and floats on water.
