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.
Why can a drop of water stay in one piece even as it falls through the air?
Surface tension of water molecules creates a cohesive force that holds the drop together. This surface tension is caused by the strong intermolecular forces between the water molecules, allowing the drop to resist breaking apart as it falls through the air.
How does a jumping spider use a water drop to its advantage in its natural habitat?
Jumping spiders use water drops in their natural habitat to hunt for prey. They can use the water drop as a reflective surface to spot potential prey and then jump towards it to catch it. The water drop also helps them to stay hydrated by drinking from it.
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.
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 do soapy water drops stay on a penny?
When soapy water is dropped on a penny, the surface tension of the water allows it to form a dome-like shape rather than immediately spreading out. The soap molecules reduce the surface tension of the water, allowing it to adhere to the penny and form a cohesive drop.
Why does sea water stay at the surface of the ocean?
Oceans are seawater throughout, not only on the surface.
Why does a card stay on a full glass of water?
A card can stay on a full glass of water because of surface tension. The cohesive forces between water molecules create a thin film on the surface that can support the weight of the card.
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 do iron filings do not sink when placed slowly on the surface of the water?
Iron filings are typically made up of very small particles with a low density, allowing them to stay afloat on the water's surface due to surface tension. The small size and shape of the filings prevent them from sinking immediately and enable them to be suspended on the water's surface before gradually sinking as the surface tension weakens.
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
