Answer with Explanation:
1. Wood charcoal is a hard, porous, highly carbonaceous product formed during the heating of wood without access of air in furnaces and retorts (sometimes in campfires as well).Charcoal is better fuel than wood because whhen the same amount of charcoal and wood are burnt, charcoal produces almost twice the heat produced by wood. Charcoal produces much less smoke than wood. Charcoal is a compact fuel that is more convenient to handle than wood.
4.Bone charcoal is a porous, black, granular material produced by charring animal bones. It is used for filtration and decolorisation.
3.Sugar charcoal is dehydrated cane sugar. It is obtained by heating the cane sugar in the presence of sulphuric acid or by heating in the absence of air. All the water content gets removed and is having only carbon.Sugar Charcoal is formed by the destructive distillation of cane sugar.
Answer:
1) a hard, porous, highly carbonaceous product formed during the heating of wood without access (or with limited access) of air in furnaces and retorts (sometimes in campfires as well). The heat of combustion of wood charcoal is 30,000-35,000 kJ/kg (7,000-8,100 kcal/kg).
Charcoal is better fuel than wood because: When the same amount of charcoal and wood are burnt, charcoal produces almost twice the heat produced by wood. Charcoal produces much less smoke than wood. Charcoal is a compact fuel that is more convenient to handle than wood.
2) Bone char is a porous, black, granular material produced by charring animal bones. Its composition varies depending on how it is made; however, it consists mainly of tricalcium phosphate 57–80%, calcium carbonate 6–10% and carbon 7–10%. It is primarily used for filtration and decolorisation.
3) Sugar charcoal is formed by the destructive distillation of cane sugar. It is also prepared by the dehydration of sugar in the presence of concentrated sulfuric acid. Since sulfuric acid is a dehydrating agent, it absorbs water from the sugar and leaves behind black residue of carbon.
