Does needle float on water?
Yes, a needle can float on water if it is carefully placed on the surface due to surface tension. However, if the needle is pushed down into the water, it will sink due to its density being greater than that of water.
What will happen to a needle place in water?
A needle placed in water will float due to surface tension. The surface tension of water allows the needle to be supported on the surface rather than sink.
Why is it that a needle may float on a clean water but sink when detergent is added to the water?
When a needle is placed on clean water, it can float due to surface tension, which is the cohesive force between water molecules at the surface. However, when detergent is added to the water, it reduces the surface tension by disrupting the cohesive forces between water molecules. This decrease in surface tension causes the needle to sink as the water can no longer support its weight.
Will a fork sink or float?
A fork will sink in water, as it is denser than water. The density of an object determines whether it will sink or float in water.
Why does needle sink when placed vertically in water but does not when placed horizontally?
When a needle is placed vertically in water, the force of gravity acting on the denser needle overcomes the buoyant force pushing it up, causing it to sink. However, when placed horizontally, the buoyant force acting on the needle is greater than its weight, allowing it to float due to surface tension and the needle's low surface area in contact with the water.

Do clothes float or sink?
it will float as long as it is not fully covered water.

Will arsenic float or sink in pure water?
Arsenic is denser than water, so it will sink in pure water.
How can a sewing needle float on the surface of water?
The needle does not break the surface tension (meniscus). Get a small piece of toilet tissue and lay it on a glass of water. lay a needle on the tissue. The tissue will become sodden and sink, leaving the needle floating on the surface tension. Put the smallest drop of washing-up liquid on the water. The surface tension will be destroyed and the needle will sink. Try it.
What liquids can a needle float on?
A needle can be made to float on very still water.
Why does a needle sink but a boat float?
The total weight of the surface area of a boat is less than than the weight of a body of water of the same size (buoyancy), so that is why it floats. A needle sinks because a body of water with the same size is lighter than the needle. Note: It is entirely possible to float a needle on water. It requires a bit of doing, but it can be done.
Will a fork sink or float?
A fork will sink in water, as it is denser than water. The density of an object determines whether it will sink or float in water.
Why needle do not flow on water?
Because needles density is higher than water

Can asphalt float on water?
Asphalt is denser than water and will sink in water rather than float.
