A visible sheen can be detected at around 60 ppm oil.
Visually oil sheen tends to have a rainbow of colors and the sheen edges tend to be smooth and gracefully curved. Mineral sheen tends to be silver in color with jagged edges and fractures running through the sheen. As oil sheen ages and the oils degrade it becomes more and more difficult to differentiate between oil and mineral sheens because the oils tend to take on the appearance of mineral sheen.
Oil sheen
I don't think bubbles actually have a color, and I don't think you can color them, but they are iridescent, like oil spots on water in parking lots. They have a rainbowish sheen, probably because they contain oil, or something oily.
No. Adding water to oil at deep frying temperature will cause a steam explosion and oil will go everywhere and burn people.
Oiling prevents rust by repelling water. As we all know, oil and water don't mix, therefore, a coat of oil (or silicone or grease or something else that repels water will keep water away from the metal parts that could rust.

Oil on top of water will settle as a thin layer, and the thickness of the layer will, due to an optical phenomena called interference, cause the thin layer to shimmer in different colors.
No it will not cause coalescence. Water separates from oil they do not mix or combine
Oil sheen
They include flat (matte), satin, semi- and hi gloss. It depends on if it is oil or water based. Varnish & stains offer different sheen options, also.
intake manifold gasket if it is coolant in the oil
Wash it. Most will go away with hot water and washing-up liquid. Get the last sheen off using a degreaser.
Some stones will use oil, some water. If you use oil, you have to use oil from then on.
No, if you have oil in your oil pan, you have other problems. It has nothing to do with your water pump going out or being bad.
It can cause your oil cap to blow right off, foam around the oil cap is more likely to be water or coolant. Get it checked right away because it can damage your engine. It's usually a sign of a bad head gasket, it lets water into the oil and oil into the water. Check your radiator to see if there is oil in the water and if the water is low.
thats oil
Your really should never put more oil then needed into anything no extra oil will not cause water to get in you obviously have a bad seal somewhere below the water line
