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.
How is surface tension important in nature?
There are technological examples of the importance of surface tension. The degree to which a liquid wets a surface or forms beads depends in large part on the surface tension. Obviously, one wants one's raincoat to bead water as well as the wax on one's car. But the opposite is true for a lubricant. One wants oil to adhere to a surface of a bearing. Coatings are designed with wettabilty as a primary consideration. Cloth may be treated with materials to prevent wetting, but that is also an example where the surface texture or roughness plays a critical role. Paint is an example of a coating that would be carefully evaluated for wettability depending on the application. Surface tension of water is obviously a property of the surface and the surface of water is an interface, i.e. the place where water comes in contact with anything else. Surface tension is really a measure of how much energy is require to create a surface of a liquid. (Liquids would rather not have much surface, that is why they form drops - to minimize the surface.) The surface tension of water is large and that surface tension determines many of the properties of any interface with water and changing the surface tension changes those properties. A lot of biology happens at the interface of one compartment of water and another and the entire reason we can even have living cells is a result of the large surface tension that stabilizes a cell membrane. Finally, all those little bugs which walk around on the top of water would have no where to live without water tension.
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.
Which property of water causes water drops to bead on s freshly waxed car?
Water molecules are sticky due to hydrogen bonds
How do you tell if beads are glass?
If you tap your glass bead on glass it will make a "sharp" sound. If you tap your bead on glass and it makes a "dull" sound, it is most likely not made of glass.
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.
What is bead board?
A bead board is a surface with a textured finish and grooves that is helpful in alligning beads. It is a very useful tool that makes the beader's task more enjoyable.

Many fabrics are coated with a water-repellent chemical that causes water to bead on the fabric instead of soaking?
This coating is a polymeric material containing fluorine; the surface become hydrophobic.
A straight pin floats on water?
Normally no. But if you carefully set the pin on some still water, yes it can 'float' on the water due to what's called surface tension. This is also what causes a small amount of water on a smooth surface to 'bead'. It's also what keeps water beetles on top of the water in ponds.

By what process does water bead on top of water?
That makes no sense. water molecules can be packed tightly together, whilst still remaining loose. Water moves around from particles bouncing into each other.
Why does a peach have fuzz?
The fuzz causes water to bead off and not cling to the skin, which makes them more resistant to some types of mold and rot.
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.
