because of its molecular structure. hey wanna go out with me? i can show you my molecular structure!

Why does water stay on a penny?
Surface tension allows water to form a large drop on a penny before popping and spilling off.
How does the water stay on a pennies?
Surface tension, place a drop of detergent on the water and it breaks the meniscus allowing the water to flow away. Also the cohesion makes the water molecules stay together. It is not because of the ridge.
How does this show that the water is denser than lavender oil.?
Add a drop of water: when it is thinking down to the bottom then it is heavier, when lighter it will stay on the upper surface, when density is equal then it floats in the middle.
How long can a bug live in a water bottle?
well it depends on what kind of bug it is! some bugs dont sink in water and they stay on the surface! they can stay there until they die when time pass or if you drop some salt on the water! or maybe if you shake the bottle a little bit ;)!
Why does a blade sink on soapy water?
You can float a razor blade on water due to the 'Surface Tension' of the water. This is the tendancy of the water molecules to stay tightly together, which is why a water drop forms a 'hump' on a surface. Soap is a 'wetting agent', or surfactant. When you add soap to the liquid, the surface tension is drastically reduced, and the water molecules 'flow' around objects, like the razor blade. So, it sinks.
Why does sea water stay at the surface of the ocean?
Oceans are seawater throughout, not only on the surface.
What are Droplets that become so large and heavy that they can no longer stay up in the air fall to earth's surface?
they are droplets of water ( the water that drops from clouds are 0.02 mm an average rain drop is 2 mm ) or they are droplets of ice (like hail)
Does warm water stay at the surface of the ocean?
As water warms, it expands. Having expanded, it is lighter, and floats at the surface- where it may be warmed more by the sunlight.
How does the water on earth's surface stay instead of dripping?
The gravity around the earth holds the water in place
Why can a sewing needle can float on the surface water in a glass?
Yes if the surface tension of the water is not broken. If you are careful you can place a needle on the surface of the water in a glass. Also if you reduce the surface tension with detergent (just a very little is enough) the needle will sink because it's density is greater than that of the water. NO (if the surface tension of the water is broken, a needle cannot float on the surface of water. This is because the needle has higher density than water (density is mass divided by volume).
Why mosquito does not sink on water surface?
Mosquitoes and other small insects can stay afloat on water because water exhibits a property called "surface tension", where a thin film "seems" to cover the water surface. This has something to do with intermolecular forces of attraction.
Why is cold ocean water murky while tropical water is clear?
Tropical waters are nutrient poor at the surface. When living things die at the surface they sink to the bottom where they decompose. The nutrients that are released when they decompose stay at the bottom because there's a thermocline--the deep water is cold and the surface water is warm and they don't mix. So the surface waters don't have much algae and stay clearer.
