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 property of water is demonstrated when you see beads of water on a waxed car hood?
surface tension, caused by the high attraction of water molecules for other water molecules.
A car has a mileage rating of 38 miles per gallon of gasoline How many miles can the car travel on 76.5 liters of gasoline?
a ar has a mileage rating of 30 miles per gallon of gasoline how many mile can the car travel on 76.5 liters of gasoline
Does water wash off gasoline?
Yes. Water will dilute gasoline and wash it off of the skin and clothing. It will also wash it off floors and car finishes. Keep any rags that have been soaked in gas in an open area to avoid fires.
How would you use gasoline in a sentence?
I went to the gas station to get some gasoline for my truck. Without gasoline in the tank, the car wouldn't run.
What gases are in a car?
There are quite a few, All i know of is Gasoline/Deisel and oil.
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.
Which property of water causes water drops to bead on s freshly waxed car?
Water molecules are sticky due to hydrogen bonds
Which property of water causes drops on a freshly waxed car?
This phenomenon is called surface tension.
Why do beads of water often form on a slippery surface such as a freshly waxed car?
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.
When can a freshly painted car be waxed?
No
When you pump gas in your car is it possible there is water in the gasoline?
Most gas stations have several filters to keep water out but water can get into the gasoline. Yes, it is possible.
What property of water is demonstrated when you see beads of water on a waxed car hood?
surface tension, caused by the high attraction of water molecules for other water molecules.
Can car fuel freeze?
Yes, but it is usually water in the gasoline that freezes.
The following is exothermic or endothermic"The combustion of gasoline in a car engine?
Gas
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.
What are the examples of cohesion?
Examples of Cohesion *Water clinging to your newly waxed car *Water clinging to a pice of waxed paper The examples above are actually examples of ADHESION not COHESION. ADHESION is the force that attracts two DIFFERENT materials together. COHESION is the sticking of two LIKE substances.
