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.
The density of rubber can vary, and the density of wood can vary even more (unless we're putting air in the rubber to make foam). In general, however, wood is less dense than rubber, rubber is less dense than copper, and copper is less dense than mercury.
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.
A tonne of what? If we assume wood, then the tonne of wood would be larger - wood is less dense than water.
Depending on what you mean by "better", it doesn't burn better. It might burn longer but it is much harder to ignite, and does not burn as hot as less-dense wood.

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.
First, the stone sinks because of the weight, the wood would probably be much lighter than the stone.Second, the density. The stone is much more dense than the wood
it is more dense

No pine is more dense then cedar.
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.
Yes. Glass and wood both vary greatly in density, but glass ranges from 2000 to 8000 kg/m3 and wood is only 350 to 1330 kg/m3 on average.Sources here: engineeringtoolbox wood-density-d_40 and here: hypertextbook facts/2004/ShayeStorm (site won't let me link but I trust you can figure it out)Whoever wrote this previous answer doesn't know what density is and should be ashamed of themselves:In fact wood is believed to be more dense than glass. For example, if you were to side wood down a wood plank it would travel at a much slower pace than it would traveling on glass. This is because wood is much more dense than glass is.
This is not a sensible question. There are many types of wood, and many types of metal. It depends which ones you pick. Balsa wood has a very low density, lignum vitae is much higher. Most woods are less dense than water (so they float) but a few are denser. Most metals are more dense than water, but a few, such as sodium and potassium are less dense. Overall, I suppose most metals are denser than most woods, but potassium is less dense than some forms of eucalyptus wood.
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.
It doesn't, sound travels faster through wood. The more dense the material the better the sound carries. Because wood is more dense than a gas such as oxygen the sound travles faster through the wood.
