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.
It depends on the car. A2 A rough surface scatters reflected light in all directions, it is harder to make out an image. A polished surface evens out surface, so that reflected light behaves more like a mirror. The wax fits into the irregularities in the paint finish. Polishing then makes this flat. For a correct image to be seen, the surface must reflect the light, back the way it came, insted of at an angle.

we can conserve water by not leaving taps running don't play with it don't give small children to play with water don't was the car everyday was it so often do close taps when u are brushing not using water and that's how we conserve water
Its due to the refraction of light. This is when the light leaves the water it speeds up causing it to change direction. To imagine this i will use an analogy of a car: Imagine a car is driving on mud (a surface with high friction) if it approaches a road at an angle, the wheels on one side will meet the road first and speed up causing the car to turn. This is similar to what happens to light.
If a car is travelling at 10 km/h in the same direction as the ship that is travelling at 90 km/h, then the car's apparent velocity with regard to the ocean is just 10 + 90 = 100 km/h.
Water molecules are sticky due to hydrogen bonds
No
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.
This phenomenon is called surface tension.
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.

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.
Viscosity measures a fluid's resistance to flow, such as honey being more viscous than water. Surface tension is the cohesive force that causes water to form droplets on a surface instead of spreading out, like when water beads on a freshly waxed car.
The property of water demonstrated is surface tension, which causes the water molecules to stick together and form droplets on the surface of the waxed car hood rather than spreading out. This is due to the hydrophobic nature of the wax, which repels water.
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.
Some examples of cohesion include water sticking to a waxed car, water beads on the floor and rain drops. Cohesion is the ability of water molecules sticking together.
depends on if you let it haze up or not
