The water extracted by the wood log while floating is of equal weight of the wood or more. For this reason, the log of wood floats while a steel needle sinks.

Can you tell why large log of wood floats on water but steel needle sinks?
Actually, the steel needle can float on water as well, so long as the surface tension is not broken. Answering the question, the buoyancy (ratio of density to that of displaced water) causes the log to float.
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.
How does a needle float on water?
the way it float is surface tension!!
Will a steel bar float in water?
I think it can float on water.
What is the orgin of the word stretch?
A needle is made of steel ; as steel is denser than water, a steel needle should sink in water because of this.
What makes a needle to float in water?
Water surface tension hold the needle on the water surface.
Why steel plates float on water?
The weight of a very thin but large (< 0.5 mm) steel plate is spread over a large area (> 0.5 m2) the surface tension of the water will stop it from sinking.
Why a large boat is able to float considering that steel is denser than water?
caz it has less dens
Will something with a lower density float on something with a higher density?
A liquid with a higher density than 1g/cm3 (one gram per cubic centimeter) (the density of water) will sink in water.
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 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.
