m_a_m_a [10]
The log will float on the water because his density is lower than the liquid, so it will stay at the top due to Archimedes' principle.

<span>Archimedes' principle is a physical law that describes the upward force (the vertical thrust) experienced by any body immersed in a fluid (liquid or gas). This force is strongly related to the density of both the fluid and the body.
