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.
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.
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.
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 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.

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 glass?

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 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.
What property of water allows a needle to float on water?
Surface tension of water is the property that allows a needle to float on water. This is due to the cohesive forces between water molecules at the surface, creating an invisible film strong enough to support the needle's weight without breaking.
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.
What happen if the needle place on a small tissue paper and very gently put the paper on the surface of water?
The tissue paper will likely float on the water's surface as long as the needle does not break through the paper. This is due to surface tension, which allows light objects to float 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.
