Why does wet paint bead up on some shiny smooth surfaces and spread evenly over other surfaces?
becuase it does
When does friction decrease?
Friction will decrease if the coefficient of friction decreases. This can be caused by having a smother surface up to a point. (When two surface are TOO smooth the friction actually increases due to molecular attraction.)
What does surface tension have to do wih floating?
surface tension relates with flotation in that the stronger the surface tension, the easier an object will float.
What makes water pile up a short distance above a containers rim?
Surface tension.
Will a paper clip float in water?
No, it isn't hollow/light enough... Improving answer: But sometimes things don't actually "float" on the water when they are really held up by surface tesion. I have heard that you can make paper clips or pins "float" on the surface of calm water.
What property of water makes it bead up on waxy surface?
The form of water you are seeing is water vapor turning to mist and then collecting on leaves.
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.
Where is a good resource for looking up water surface textures to determine what is happening below the surface Smooth then choppy etc?

Does the scuba Neoprene cell phone case bead up with material after a short period of ware?
Neoprene cases are known to retain their smooth surface even after months of use. Beading should not be an issue.
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.

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 is it that wax paper does not get wet when you sprinkle water on it?
Water doesn't stick to wax because there is no adhesion meaning the molecules don't stick to the wax, but they stick to each other, also known as hydrogen bonding. This causes the water to bead up and take up the least surface space it can. They are attracted to groups on a hydrophilic surface (water-loving) such as glass.
What gives a smooth surface when polished?
The preparation of the surface before polishing and ultimately the application and buffing up of the polish.
What happens when light is reflected off a smooth surface?
it reflicts back up
Does CH3OH bead up or spread out on wax paper why?
methanol is a pretty non-polar solvent so it can dissolve the wax(long chain hydrocarbon) on waxpaper and it also has lower surface tension than water
Why does water bead up on freshly waxed car?
Wax is hydrophobic, meaning it repels water. Of course, this repulsion is not strong enough to make the water hover a millimeter above the surface, but it is strong enough to force the water to act in this way, rather than sit there in a thin sheet. The "surface tension" of the water itself also plays a role.
