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).
Cold water sinks, hot water rises.
Teak, ebony, mahogany.
Well it wasn't Natalie Wood because Natalie Wood sinks in water.
pine wood?
the density of water is higher than the density of wood... & so an iron piece sinks & a ton of wood floats...
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.
The pebble is heavier than water so it sinks. The wood isn't heavier than water so it floats.
The liquid is water, the rock here is pumice and the wood mentioned here is ironwood.
yes, wood eventually becomes waterlogged and sinks, plastic does not become waterlogged.
Wood floats on water, but iron sinks into it.
Would you chop this wood for me? is an example
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.
