Why does water bead up on a waxed car but gasoline spreads out?

∙ 14y ago
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.
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.
When was Bang Bead created?
Bang Bead was created in 2000.
What is the function of bead in the pipette?
The rationale of the bead in the WBC pipette is for recognition. Through the white bead present inside the pipette it would be easy for a medical technologist to determine the pipette that should be used for differential counting. Aside from identification purposes, white bead is also used as a signal during the shaking procedure that would indicate that the components inside the pipet are mixed.
What is the principle behind borax fusion test?
The bead of borax with some powdered sample is heated in a flame; the color of the bead is specific for each element and is used as a qualitative analysis.
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.
Which property of water causes water drops to bead on s freshly waxed car?
Water molecules are sticky due to hydrogen bonds

Sometimes they do, but most of the times i saw were with bed spreads!!!!!!!! hope I helped
How do you kill bugs inside beads?
you pour gasoline on the bead and let it dry or call an exterminator because the bead is most likely not safe to sleep on.

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.
