The simple answer is yes it can float until it becomes waterlogged.
No, charcoal does not float on oil because it is denser than oil. Charcoal is made from carbon-rich materials and typically sinks in liquids like oil due to its higher density.
A piece of charcoal is heavier than water but it floats due to it's highly porousness
Water is about 5 times more dense than charcoal. Charcoal floats. (Anything less dense than water floats. More dense than water, it sinks in water)
Because that piece of charcoal is lighter that the water, so it floats.
Charcoal is actually heavier than water with a density ranging from 180kg/m3 to 220kg/m3 ,but wood charcoal is porous with many holes in it and contains air this helps in its floating while when air is removed by boiling it settles down
The only way that charcoal (whether of wood, animal, etc.) can float on water is if the total mass of the charcoal is less than the total mass of an equivalent volume of water. This means that the charcoal is not heavier than water, at least not an equal volume of water. If the charcoal was heavier than (an equivalent volume of) water, it would not float.
To separate powdered charcoal from a mixture containing copper oxide, just add water. Charcoal is considered quite a bit less dense than water and one set of tables gives the density as circa 400 kg.m-3 . Copper oxide is much more dense than water or charcoal. So the copper oxide will sink to the bottom and the charcoal will float to the top of the water. This can now be decanted and filtered leaving the charcoal on the filter paper which can be dried and to leave charcoal. Then with a separate filtration, the copper oxide and traces of water can be filtered and then dried.
Coal is a synonym for charcoal.
Charcoal is mostly carbon.

Pass me the charcoal please.I enjoy a charcoal barbecue in the summer.
