why a large log of wood floats on water but steel needle sinks?
Answers
Answer:
The wood floats because it is less dense than water and the buoyant force due to the displaced fluid will be greater than the weight force of the wood. ... Metal is more dense than water and hence will sink. However a needle can be made to float on the water if it does not break the surface
Answer:
The wood log floats and the needle does not because of there densities
Explanation:
it is so because the intere molecular forces between the wood log are quiet open due to which it has inter molecular spaces and causes have a less density as compared to water making it float whereas the molecules of the needle are tightly packed having very less inter molecular space causes it having higher density than water which makes it sink.
Completely explained the concept hope u understand
