The liquid is water, the rock here is pumice and the wood mentioned here is ironwood.
A log of wood sinks in water because wood is more dense than water. The density of an object determines whether it sinks or floats in a liquid. Since the density of wood is greater than that of water, the log sinks.
Whether a piece of wood floats or sinks in water depends on the density of the wood. If the wood has a lower density than water, it will float. If it is denser than water, it will sink. Wood is usually less dense than water, so it typically floats.
A pebble sinks in water because its density is higher than that of water, causing it to displace less water and ultimately sink. In contrast, a piece of wood floats on water because its density is lower than that of water, allowing it to displace enough water to create an upward buoyant force that supports its weight.
A large log of wood floats on water because its density is less than that of water, allowing it to displace enough water to overcome gravity and float. In contrast, a steel needle sinks because its density is greater than that of water, causing it to displace less water than its own weight and sink.
ans.1. wood can be float on oil because it is a thick, hard, and heavy object. 2.the bottle can not float on oil because it is not thick, hard, and, not heavy object. that's why it can not float

pine wood?
One way to distinguish cork from wood is by determining their buoyancy in liquids. Cork is lightweight and floats in water, while wood is denser and sinks. Therefore, you can use water as the liquid to distinguish between cork and wood based on their buoyancy characteristics.
Wood floats on water, but iron sinks into it.
Would you chop this wood for me? is an example
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.
Whether a piece of wood floats or sinks in water depends on the density of the wood. If the wood has a lower density than water, it will float. If it is denser than water, it will sink. Wood is usually less dense than water, so it typically floats.
The water extracted by the wood log while floating is of equal weight of the wood or more. For this reason, the log of wood floats while a steel needle sinks.
A pebble sinks in water because its density is higher than that of water, causing it to displace less water and ultimately sink. In contrast, a piece of wood floats on water because its density is lower than that of water, allowing it to displace enough water to create an upward buoyant force that supports its weight.
Objects that are less dense than water will float, while objects that are denser than water will sink. For example, wood, plastic, and cork typically float in water, while metals like lead and iron sink. The shape and size of an object can also affect whether it floats or sinks.
Because that piece of charcoal is lighter that the water, so it floats.
Something has neutral bouyancy if it stays in the water wherever you put it, only if it has the same density as the water - there is no cause for it to float or sink than the volume of water it has displaced. If its density is more, as for a stone, it must be heavier than that so it sinks. For wood, it is lighter so water from above drops down as the wood rises.
