In their 2009 paper "Towards a worldwide wood economics spectrum"
published in Ecology Letters 12(4), J. Chave, D.A. Coomes, S. Jansen,
S.L. Lewis, N.G. Swenson, and A.E. Zanne listed 16,468 species of wood,
of which oven-dry fresh samples of 240 items on the list have densities
greater than 1 gm/cm3 .
Skimming the short-list for names that I recognize, I see several varieties each
of Eucalyptus, Acacia, Mimosa, Diospyros (ebony), and Tectona grandis (teak).
Pine wood sinks in water because it is denser than water. The wood's cellular structure and composition cause it to have a higher overall density, resulting in it sinking when placed in water.
A log of wood sinks in water because wood is more dense than water. The density of an object determines whether it sinks or floats in a liquid. Since the density of wood is greater than that of water, the log sinks.
Well it wasn't Natalie Wood because Natalie Wood sinks in water.
pine wood?
Something has neutral bouyancy if it stays in the water wherever you put it, only if it has the same density as the water - there is no cause for it to float or sink than the volume of water it has displaced. If its density is more, as for a stone, it must be heavier than that so it sinks. For wood, it is lighter so water from above drops down as the wood rises.
No, ironwood does not float. It is a dense and heavy type of wood that sinks in water.
yes, wood eventually becomes waterlogged and sinks, plastic does not become waterlogged.
Would you chop this wood for me? is an example
Wood floats on water, but iron sinks into it.
Denser water, such as saltwater, is more likely to sink in freshwater because of its higher density. This phenomenon can occur in bodies of water with different salinity levels, where the denser water sinks beneath the less dense water.
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.
Whether a piece of wood floats or sinks in water depends on the density of the wood. If the wood has a lower density than water, it will float. If it is denser than water, it will sink. Wood is usually less dense than water, so it typically floats.
