Question

Why does wood float in water?

Answer 1

wood floats on water because it is less dense than water. Wood is made of individual fibers, and there is some space in between these fibers. Because of this, most woods will naturally float. Woods with denser fibers and those with little space between fibers, however, will sink. In addition, some wood will float until it is saturated with water, at which point it also will sink. Dense wood can still be used for making boats because the air inside of the boat lowers its total displacement.
