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.
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.
What makes a needle to float in water?
A needle can float on water due to surface tension. When the needle is carefully placed on the surface of the water, its weight is not enough to break the surface tension created by the water molecules, causing it to float.
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.
If you lay a steel needle horizontally on water it will float if you place the needle vertically into the water it will sink explain why?
Needle floats if u place it on the surface of the water even its density is heavier than water because there is a thin film on the water surface that is stretched towards the sides of the container because of the collision force of the molecules & this is called suface tension when u plae the needle vertically it tears the film therefore it sinks

Why would a needle flaot on the water?
A needle can float on water due to surface tension. The surface tension of water is strong enough to support the needle and prevent it from sinking, as long as the needle is carefully placed on the water and doesn't break the surface tension.
Can you float a needle?
Yes, you can float a needle I have done it before. It doesn't have to do with density though it has to do with surface tension.
Why can a sewing needle can float on the surface of water in glass?
Surface tension
Explain why a swing needle can float on the surface of water in a glass?
Due to surface tension, the upper surface of water acts like a stretched membrane which enables it to float a swing needle.
Why can a sewing needle can float on the surface of water in a glass.?
A sewing needle can float on the surface of water due to a property called surface tension. Water molecules at the surface are more attracted to each other than to the air above, creating a "skin-like" barrier that can support the weight of the needle. This allows the needle to stay afloat instead of sinking.
How does a needle float on water?
A needle can float on water due to surface tension. The water molecules at the surface stick together, creating a "film" strong enough to support the needle's weight without it sinking. This phenomenon is also why some small insects like water striders can walk on water.
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.
