For fish tanks you want activated charcoal to filter the water. Deactivated charcoal is just charcoal.
Well ehen they float in the water that means there dead.you dumney
In fresh water a good egg will sink. If you put an uncooked egg in water and it floats, throw it away. A boiled egg will float, and in a strong concentration of salt water, an egg will float.
I've seen some float... I don't think they'll live long in water, though.
Dead bodies float due to the gases produced during decomposition. The gases are lighter than the water, causes the body to float and to continue decomposing
I think it does
Because that piece of charcoal is lighter that the water, so it floats.
A piece of charcoal is heavier than water but it floats due to it's highly porousness
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.
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)
The simple answer is yes it can float until it becomes waterlogged.
Depends on what the charcoal is made of, some sinks, some floats.
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.
Charcoal will not dissolve in water
No. Carbon is not water soluble.
Yes, charcoal floats in water.
A boat can float on the water, and a submarine can float in the water.
