Detailed Solution

The above statement is True.
When we burn wood with a limited supply of oxygen and water, few materials in it get removed to leave a residue known as charcoal. Charcoal is widely used as a fuel since it burns without flames, is relatively smokeless and has higher heat generation efficiency.
The uses of wood charcoal are:
●       It is porous and can absorb liquids and gases on its porous surface. Therefore, it is used in water filters and gas masks.
●       It is used as a decolorizing agent.
●       It is an important component of gunpowder.
