It depends on the kind of wood. Water is more dense than most wood, but there are some kinds of wood (typically called ironwood) that are more dense than water.
Most wood seen on a common basis is less dense than water. These woods floats on water. Some more exotic woods are more dense than water and sink when placed in water.
It may or may not float. It depends on whether the entire piece of wood is less dense than the water. Most wood is and will float on water. Very dense woods, such as ebony and cocobolo are more dense than water and will sink.
Ice! Some wood is also less dense than water. Styrofoam and some plastics are also less dense than water. There is an EXTREMELY simple experiment to test for this. Any object that floats when placed in water is less dense than the water it is in.And of course sperm.
No pine is more dense then cedar.
Wood in most cases
Ironwood is the most dense wood in existance. Petrified wood is considered rock. Ironwood is so dense, it will not float on water. See the related link for more information.
on top. Wood is less dense than water to the point that it float on top of water, and salt water is more dense and has a higher surface tension than pure water so the wood would, if possible, float higher.
If water is at a liquid state, its molecules are able to roll;therefore, water's composition would deem water less dense than wood.
The average density of the wood is less dense than water, while the metal of a coin is more dense than water. If you weigh equal volumes of each, you will see the difference in density.
Boyle's Law - upthrust equals the weight of fluid displaced, so the more dense fluid (salt water) will cause the wood to float higher than the less dense fluid (pure water).
Floating and sinking is related to density - if something is more dense (i.e. has more mass per volume) than the fluid it will sink, and if it is less dense then it will float. This is why wood floats in water, and helium balloons float in air - helium is less dense than air and wood is less dense than water. Steel ships float because, although they are made of steel which is more dense than water, the air inside them is less dense than water so the overall effect is floating.
Because the piece of wood is less dense than the water
