No. Magma varies in density, but it will be less dense than a solid rock of the same composition.
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.
A rock will sink because it is more dense than the liquid into which it is placed.
No pine is more dense then cedar.
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.
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.
Mafic rock is on average more dense.

No. Molten rock expands due to heat as the molecules get excited, therefore it is less dense than solid rock.
Anything as dense or more dense than the rock. Rocks, sledge hammers, chisels, etc
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.
rock is denser than gas because it is a solid
