The rainbow-colored film that gasoline or oil forms on a puddle is one indication that hydrocarbons are not what?
The rainbow-colored film that gasoline or oil forms on a puddle is one indication that hydrocarbons are not soluble in water
Why a Puddle of water shows with a rainbow effect on pavement?
This is an example of thin-film interference. Oil on the pavement floats to the water's surface, forming an extremely thin film. Light waves reflected from the front and back surfaces of the film interfere, amplifying a particular light wavelength (color) for each particular film thickness. The rainbow pattern is formed by gradual changes in film thickness across the puddle surface.
Why does a drop of water placed on the surface of oil contracts to form a spherical shape?
The surface tension of the water and the fact that oil and water cannot wet each other.
How would you separate oil and water into their components?
A mixture of oil and water is heterogeneous. Oil naturally separates from water and they can be separated by skimming the surface off the water.
How do you separate water from synthetic oil?
Just let the oil float to the surface and skim it off.
Does cooking oil have more surface tension than water?
Because of the polarity of the water molecule, hydrogen bonds form between them. This results in the higher surface tension. Oil is nonpolar, so hydrogen bonds do not form between the molecules, so the surface tension is less.

Can you separate oil from a puddle?
No, oil can't be mixed with anythingexcept for itself. You couldn't separate oil puddle of water if that's what you mean. You'd have to have some fancy gadget like scientists use for things like that. In other words, you could not.

Why does a drop of oil placed on the surface of water spread over the entire surface?
because the water has more density than the oil so the oil spreads only on the surface.
How does motor oil effcet water?
Motor oil is insoluble in water and it is denser in water. Therefore, motor oil will not mix with water. It will remain separate.
Why does oil in a bowl of water get repelled when washing liquid is dropped on it?
The oil is not repelled. It is floating on the surface of the water as a thin film. Water has very high surface tension, but when soap or detergent is added to water that surface tension suddenly drops. The water surface now contracts like a punctured rubber sheet toward the remaining area of high surface tension, dragging the oil film floating on its surface with it.
Why does oil float on the surface of water?
Because oil is less dense than water.
Why the oil stays on the surface if you mixed in water?
Oil is not as dense as water. So, even when they are mixed, the water molecules can still slide down in between the oil molecules, thereby causing the oil molecules to form a layer on the surface of the water.
How does an oil slick form when an oil tanker springs a leak?
Oil and water do not mix. Oil floats to the surface of the water.
Would oil alter the boling point of water?
Oil is not soluble in water; the boiling point remain unchanged.
Is USP mineral oil soluble in water?
No, it is not. Oil and water do not mix. If you pour oil into water, the oil will float to the surface. If you pour water into oil, the water will sink to the bottom and the oil will float on top.
