No its a solid
It is caused by the difference in density between wood and water.One cubic foot of wood is usually lighter than one cubic foot of water, hence the water goes up a little but the wood goes up more.The overall density of the wood block is less than that of the water, so it floats.The basic principle is that when a solid object is immersed in a fluid, the solid displaces some of the fluid. This causes an upthrust on the solid, equal to the weight of fluid displaced. If the upthrust is equal to the weight of the solid it floats.
I haven't tried it on wood but lighter fluid seems to get most things off. Acetone too, but it might damage the wood.
A block of wood floats higher in saltwater because saltwater is denser than fresh water, providing more buoyant force. The increased density of saltwater displaces more water, pushing the block of wood higher above the surface compared to fresh water.

The buoyant force acting on the wood is equal to the weight of the water displaced by the wood. This is known as Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object.
Either with a blow torch or by painting with a fungicidal dry rot fluid or fence and shed treatment.
WOW. I think this just may be the stupidest question I have ever seen asked.
Objects sink or float depending upon their densities. For example wood floats on water because the density of wood is less than that of water, while a piece of iron would sink in water as its density is more than water.
Wood is more buoyant than metal because wood has a lower density than metal. Buoyancy is a result of the object's density compared to the density of the fluid it is in. Since wood is less dense than metal, it displaces more water and experiences an upward buoyant force that keeps it afloat.
Wood vinegar or pyroligneous acid is fluid or sap taken from tree cells. It is said to be useful for mild pain relief, detoxification of the body, decreasing swelling in the body and for sterilizing and healing minor wounds.
Wood floats on water because it is less dense than water. When an object is less dense than the fluid it is placed in, it will float. The air pockets within the wood contribute to its buoyancy, keeping it afloat on the water's surface.
Materials that are less dense than the fluid in which they are placed will float or be buoyant. This can include materials such as wood, plastic, cork, and some metals like aluminum. However, the buoyancy of a material also depends on its shape and how it is distributed in the fluid.
