Why does wet paint bead up on some shiny smooth surfaces and spread evenly over other surfaces?
becuase it does
Why does water bead up on a waxed car but gasoline does not?
Most waxes are petroleum based, just like gasoline. Therefore, they have similar properties and mix, whereas water has significantly different properties, causing it to 'bead up' and form droplets on the surface.
Why does water bead up on a waxed car but gasoline spreads out?
A waxed car is not hydrophilic, it is not wetted with water. A drop of water falling on such a surface does not speak out wetting the surface. Instead the surface tension of the water drop pulls it into a spherical shape that sits on top of the surface until it either slides off or evaporates.
If you paint high gloss acrylic over high gloss oil on the trim will it peel off?
the high gloss acrylic would bead up and not give you an even application over the oil based
Would mercury bead up more on a waxed or unwaxed car?
Short Answer:One expects mercury, like water, to bead more on a waxed surface and less on a painted or metallic surface.Explanation:The phenomena of beading of any liquid depends on the density of the liquid and the interfacial surface tension between the liquid and the surface with which it is in contact.Mercury has a large surface tension normally. The mercury-air interface has a surface tension of about 482 dynes/cm compared to water-air which is about 72 dynes/cm. Both of these are larger than most other liquids. The water-mercury interface has a surface tension of 415 dynes/cm.Both water and mercury decrease surface tension when in contact with a polar medium such as an alcohol.Wax is very non-polar while paint is presumably slightly polar. Of course, metal would be more polar. (Perhaps polarizable is a better term.) One expects mercury, like water, to bead more on a waxed surface and less on a painted or metallic surface.
Why does H2O bead up into tiny droplets?
i do not know :D
What are the benefits of oil?
Oil is used as a lubricant in an engine. The oil gives a thin coat to metal surfaces, preventing metal to metal contact. This makes the components run smoother and last longer. Without oil, an engine will freeze up in a mater of minutes.
Can wax on car not bead up and still be good?
depends on if you let it haze up or not
