Does the needle float or sink in water?
A needle sink in water.
How does a needle float on water?
the way it float is surface tension!!
What makes a needle to float in water?
Water surface tension hold the needle on the water surface.
Why does the needle float when it is dropped in water parallelaly and why it sinks when dropped perpendicularly?
i think that vol of water underneath the needle when it is dropped on water parallely is more which prevents the needle from sinking.
What will happen to a needle place in water?
It will float if placed carefully enough.
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.
Does the needle float or sink in water?
A needle sink in water.
What liquids can a needle float on?
A needle can be made to float on very still water.

Why can a sewing needle can float on the surface of water in glass?
Surface tension
Why can a sewing needle can float on the surface of water in a glass.?
Surface tension
Which property of water allows things to float?
There is NO property of water that allows things to float. Floating in not a property of a substance. It is the difference in density of two objects that allows one to be buoyant when surrounded by the other. This a balloon can float on air, A steel ship can float on water and oil can float on water.
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 is it that a needle may float on a clean water but sink when detergent is added to the water?
Because the detergent reduces the surface tension of the water.
