How can a wet surface affect friction?
Water can make a flat surface more slippery, which will decrease the amount of friction
Why is the road is most slippery when it begins to rain?
As rain falls, the water mixes with oil found on the road's surface, making the pavement slippery.that we use the alakalis to the litmus paper
Is thin oil more slippery than thick oil?
No. A thinner oil would be just like water so it wouldn't stick unless it was on a slippery surface. But the thicker the oil the slippery it will be.
What the is thermocline?
The transition layer between the mixed layer at the surface and the deep water layer.
What happens when water is mixed with cyclohexane?
they are immiscible cyclohexane floats on water surface.
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.
Why the oil stays on the surface if you mixed in water?
Oil is not as dense as water. So, even when they are mixed, the water molecules can still slide down in between the oil molecules, thereby causing the oil molecules to form a layer on the surface of the water.
How can water from earth's surface create caves?
Erosion
How does water play a role in shaping the surface of the earth?
Water can create caves.
What causes the oceans surface water to be warmer than water in the mixed zone or deep zone?
The sun’s rays hit the surface directly.
Many roads are most slippery when it first starts to rain or snow because?
Accumulated oil residue from the traffic flow during dry weather becomes wet and moves to the surface of the travelled lanes because oil is lighter than water. This makes the road surface extermely slippery.
What body of water has the lowest density?
Surface mixed zone
